SUMMARY:Seminar on Tuesday\, 15 May 2018 at 2pm
DESCRIPTION:Title: Modified Inferential Methods on Restricted Parameters in Multivariate Regression Analysis: Applications in Socio-demographic Research \nSpeaker: Sheikh Mohammad Sayem\n\n               PhD Researcher\, ISRT\n \nAbstract: Multivariate regression analysis is getting increasing attention among the socio-demographers due to the complex nature of the interdependence of the response variables. This PhD research is to carry out detailed study on restricted parameters of multivariate regression analysis with continuous\, discrete or mixed responses to seek out or develop efficient point estimation strategy and hence develop appropriate hypothesis testing procedure for hypothesis involving restricted parameters.This seminar will give a clear idea about the specific objectives of the PhD research and about the way how the objectives will be met in line of the existing literature. In this study\, a modified maximum likelihood estimation technique is primarily used for estimating restricted parameters of multivariate regression analysis with continuous responses. A Monte Carlo simulation is carried out to evaluate the performance of the estimators. The relative efficiency of the modified maximum likelihood estimator is found to be higher than the ordinary least square or maximum likelihood estimators.

SUMMARY:Seminar on Tuesday\, April 8 at 2 pm
DESCRIPTION:Title: Approximation of the Formal Bayesian Model Comparison using the Extended Conditional Predictive Ordinatecriterion\n\nSpeaker: Md. Rashedul Hoque\, Assistant Professor\, ISRT\n \nVenue and Time: ISRT seminar room\, 2 pm\n\nAbstract: The optimal method for Bayesian model comparison is the formal Bayes factor (BF)\, according to decision theory. The formal BF is computationally troublesome for more complex models. If predictive distributions under the competing models do not have a closed form\, a cross-validation idea\, called the conditional predictive ordinate (CPO) criterion can be used. In the cross-validation sense\, this is a ‘leave-out one’ approach. CPO can be calculated directly from the Monte Carlo (MC) outputs\, and the resulting Bayesian model comparison is called the pseudo-Bayes factor (PBF). We can get closer to the formal Bayesian model comparison by increasing the ‘leave-out size’\, and at ‘leave-out all’ we recover the formal BF. But\, the MC error increases with increasing ‘leave-out size’. In this study\, we examine this for linear and logistic regression models.\nOur study reveals that the Bayesian model comparison can favor a different model for PBFcompared to BF when comparing two close linear models. So\, larger ‘leave-out sizes’ are preferred which provide result close to the optimal BF. On the other hand\, MC samples based formal Bayesian model comparisons are computed with more MC error for increasing ‘leave-out sizes’; this is observed by comparing with the available closed-form results. Still\, considering a reasonable error\, we can use ‘leave-out size’ more than one instead of fixing it at one. These findings can be extended to logistic models where closed form solution is\nunavailable.

SUMMARY:Seminar on Tuesday\, April 17 at 2 pm
DESCRIPTION:Title: Evolution of Reproductive Health in Bangladesh\n \nSpeaker: Dr. Halida Hanum Akhter \n               Faculty Member \n               Bloomberg School of Public Health \n               John Hopkins Deltin 7 Aviator গেম টাকা ইনকাম\, Baltimore\, USA\n\nVenue: ISRT seminar room\n               \n\nAbstract: \nIn Bangladesh\, the government family planning program started in 1965 and at NGO level in around 1952. The government program was a vertical program with only IUD (intra uterine device) and high dose oral pills as a pilot program. With a demonstration project on post-partum tubal ligation in four urban clinics\, under the Family Planning Board\, the program was implemented in the whole country. In 1974\, MFSTC (Mohammadpur Fertility Services and Training Center) started as a special project of Ministry of Health and Family Planning\, Then around 1978 family planning and MCH was integrated and named MCH based family planning program. Subsequently in 1994\, ICPD (International  Conference on Population and Development) also named as Cairo conference where Reproductive health concept and definition was introduced\, vetted and cosigned by 198 countries of the world. All these countries were the cosignatory of this ‘program of action’ document and agreed to introduce reproductive health in the country program. Reproductive health is a rights based approach committing to address Life Cycle approach to women’s health issues.  Since 1994\, many international instruments\, such as ICPD POA\, ICPD +5\, ICPD +15 monitored programs nationally and globally. \nThe speaker talks about the accomplishment thus far and the unfinished agenda in reproductive health in Bangladesh.

DESCRIPTION:Title: Panjer Recursion to evaluate total claim distribution recursively\n\n \nSpeaker: Dr. Abdul H. Sharif\n              Adjunct Professor\n              Mathematical Sciences Department\n              Central Connecticut State Deltin 7 Aviator গেম টাকা ইনকাম\, USA. \n   \nAbstract: The usual method of evaluating the distribution function of the total claims incurred in a fixed period of time\, requires the computation of many convolutions of the conditional distribution of the amount of a claim given that a claim has occurred. When the expected number of claims is large\, the computation can become unwieldy even with modern large-scale electronic computers. In this presentation\, a recursive definition of the distribution of total claims is developed for a family of claim number distributions and arbitrary claim amount distributions. When the claim amount is discrete\, the recursive definition can be used to compute the distribution of total claims without the use of convolutions. This can reduce the number of required computations by several orders of magnitude for sufficiently large portfolios.\n\nFinally\, I will discuss some current research on total claim modeling. Assuming the diversified level of the audience\, the level of mathematics will be kept to probability generating function(PGF) and moment generating function (MGF).

The objective of public speaking is to inform\, persuade or to entertain the audience. It helps in skill building\, professional credibility\, networking and finding suitable jobs. As an applied statistician it is a challenge how we communicate with our audience including our students\, colleagues and consulting clients. My talk will concentrate on: Benefits of Public Speaking\, Steps in Successful Public Speaking and Resources Available to Improve Public Speaking. Toastmasters International club (www.toastmasters.org) is a great way to learn how to formulate\, express\, and sell your ideas and yourself with confidence. I will share with you my experience with this club and how it works. My recommendation will be to join such a club to improve your skills in public speaking and leadership.

DESCRIPTION:Title: Survival Ensembles and Representative Trees for Cancer Prognostication\n \nSpeaker: Mousumi Banerjee\, PhD\n              Research Professor of Biostatistics\n              School of Public Health & Comprehensive Cancer Center\,\n              Director of Biostatistics\n              Center for Healthcare Outcomes and Policy\n              The Deltin 7 Aviator গেম টাকা ইনকাম of Michigan\, Ann Arbor\, USA.\n    \n Abstract: Tree-based methods have become popular for analyzing right censored survival data where the primary goal is the prognostic stratification of patients. Ensemble techniques such as random forest improve the accuracy in prediction and address the instability in a single tree by growing an ensemble of trees and aggregating. However\, individual trees are lost in the forest. This talk will first provide an overview of the methodological aspects of tree-based modeling in the censored data setting. Next\, we propose a methodology for identifying the most representative trees in a forest for survival data\, based on several tree distance metrics. For any two trees\, the metrics are chosen to (1) measure similarity of the covariates used to split the trees; (2) reflect similar clustering of patients in the terminal nodes of the trees; and (3) measure similarity in predictions from the two trees. While the latter focuses on prediction\, the first two metrics focus on the architectural similarity between two trees. The most representative trees in the forest are chosen based on the average distance between a tree and all other trees in the forest. Out of bag estimate of error rate is obtained using neighborhoods of representative trees. Simulations and data examples show gains in predictive accuracy when averaging over such neighborhoods. Although our focus is on trees for censored data\, the ideas are also applicable to classification and regression trees. We illustrate our methods using data from a thyroid cancer study.

DESCRIPTION:Title: Conditional dependence in joint modelling of longitudinal non-Gaussian outcomes\n \nSpeaker: Mili Roy\, MSc\n              Research Assistant\n              Werklund School of Education\n              Deltin 7 Aviator গেম টাকা ইনকাম of Calgary\, Canada \n   \nAbstract: The study is motivated by the limitations of conventional joint modelling strategies based\n\n\non linear and generalized linear mixed models (LMMs/GLMMs). The class of so-called Gaussian\ncopula mixed models (GCMMs)\, introduced by Wu and de Leon (2014) to generalize conventional\nLMMs/GLMMs to non-Gaussian settings\, was adopted\, and simulations were conducted to in-\nvestigate the impact of incorrectly ignoring the conditional dependence between outcomes\, given\nthe random effects\, on the performance of maximum likelihood estimates (MLEs). A variety of\nscenarios involving shared or correlated random effects were considered\, and implementation of\nthe correct and misspecied joint models was done in SAS’s PROC NLMIXED. Although MLEs of\nfixed effects were only slightly impacted by the conditional independence misspecication\, MLEs\nbased on the correct GCMM yielded generally better performances than those from the incorrect\nmodel. Data on pediatric pain (Weiss\, 2005; Withanage et al.\, 2015) were used for illustration.

DESCRIPTION:Title: Spectrum sharing in cellular networks: Optimisation and post-optimisation techniques\n \nSpeaker: Md Asaduzzaman\, PhD\n              Associate Professor\n              ISRT\, Deltin 7 Aviator গেম টাকা ইনকাম of Deltin 7 \n \nAbstract: \n\nDynamic spectrum sharing aims to provide secondary access to under-utilized spectrum in cellular networks. The main aim of the talk is twofold. Firstly\, the secondary operator aims to borrow spectrum bandwidths under the assumption that more spectrum resources exist considering a merchant mode. Two optimization models are proposed using stochastic and optimization models in which the secondary operator (i) spends the minimal cost to achieve the target grade of service assuming unrestricted budget or (ii) gains the maximal profit to achieve the target grade of service assuming restricted budget. Results obtained from each model are then compared with results derived from algorithms in which spectrum borrowings are random. Comparisons showed that the gain in the results obtained from our proposed stochastic-optimization framework is significantly higher than heuristic counterparts. Secondly\, post-optimization performance analysis of the operators in the form of blocking probability in various scenarios is investigated to determine the probable performance gain and degradation of the secondary and primary operators respectively. We mathematically modelled the sharing agreement scenario and derive the closed form solution of blocking probabilities for each operator. Results showed how the secondary operator perform in terms of blocking probability under various offered loads and sharing capacity.

DESCRIPTION:Title: Energy Expenditure Prediction from Raw Accelerometer  Data: A Comparison between Linear and Nonlinear Models\n\nSpeaker: Dr. Munni Begum\n              Professor of Mathematical Sciences\n              Ball State Deltin 7 Aviator গেম টাকা ইনকাম\, USA\n\nAbstract:\n\nThis study had three purposes\, all related to evaluating energy expenditure (EE) prediction accuracy from body-worn accelerometers: (1) compare linear regression to linear mixed models\, (2) compare linear models to artificial neural network models\, and (3) compare accuracy of accelerometers placed on the hip\, thigh\, and wrists. Forty individuals performed 13 activities in a 90 min semi-structured\, laboratory-based protocol. Participants wore accelerometers on the right hip\, right thigh\, and both wrists and a portable metabolic analyzer (EE criterion). Four EE prediction models were developed for each accelerometer: linear regression\, linear mixed\, and two ANN models. EE prediction accuracy was assessed using correlations\, root mean square error (RMSE)\, and bias and was compared across models and accelerometers using repeated-measures analysis of variance. For all accelerometer placements\, there were no significant differences for correlations or RMSE between linear regression and linear mixed models. For the thighworn accelerometer\, there were no differences in correlations or RMSE between linear and ANN models. Conversely\, one ANN had higher correlations and lower RMSE than both linear models for the hip and both ANNs had higher correlations and lower RMSE than both linear models for the wrist-worn accelerometers. For studies using wrist-worn accelerometers\, machine-learning models offer a significant improvement in EE prediction accuracy over linear models. Conversely\, linear models showed similar EE prediction accuracy to machine learning models for hip- and thigh-worn accelerometers and may be viable alternative modeling techniques for EE prediction for hip or thigh-worn accelerometers.

DESCRIPTION:Construction of Ensembles by Exploiting the Richness of Feature Variables in High-Dimensional Data with Application in Protein Homology\n\n\nMay 23\, 2017 – 7:13pm \n\n\n\nFull Title:\nConstruction of Ensembles by Exploiting the Richness of Feature Variables in High-Dimensional Data with Application in Protein Homology\n\n\nSpeaker:\nDr. Jabed Tomal\n\n\n\nAssistant Professor\nDepartment of Computer and Mathematical Sciences\nThe Deltin 7 Aviator গেম টাকা ইনকাম of Toronto Scarborough\, Canada.\n\n\nDate/Time:\nMonday\, May 29\, 2017\, 10 a.m.\n\n\nVenue:\nISRT seminar room\n\n\n\n  \n\nABSTRACT\nHigh-dimensional data may contain complementary subsets of useful feature variables which could bevaluable in predicting a response. In this work\, I have developed a predictionmodel which exploits the richness of information contained in the complementary subsets ofuseful feature variables in high-dimensional data. The proposed model – which is an aggregated collection of logistic regression models (LRM) – is called an ensemble\, where each constituent LRM is fitted to a subset of feature variables. An algorithm is developed to cluster the feature variables into subsets in a way that the variables in a subset are good to put together in an LRM\, and the variables in different subsets are good in separate LRMs. Each subset of variables is called a “phalanx”\, and the resulting ensemble is called an “ensemble of phalanxes (EPX).” The strength of the ensembledepends on the algorithm’s ability to identify/output strong and diverse subsets of feature variables.\nHomologous proteins are considered to havea common evolutionary origin\, i.e.\, the bearers of homologous proteins share a common ancestor. To develop an evolutionary sequence of proteins\, a scientist needs to predict their biological homogeneity. The proposed ensembleis applied to the protein homology data\, obtained from the 2004 KDD cup competition\,and used to predict biological homogeneity of proteins. In this application\, the feature variables are various scores representing structural similarity and amino acid sequence identity of proteins. Theunderlying assumption\, for model building\,is that the structural similarity and amino acid sequence identityare predictive to proteins’ biological homogeneity.As the proportion of homologous proteins is rare\, the prediction performances of theensemble are evaluated by checking its ability to rank rare homologous proteins ahead of the non-homologous proteins. While prediction performances of an EPX are competitive to contemporary state-of-the-art ensembles\, a big leap of improvement in prediction performances is achieved by aggregating two diverse EPXs obtained from optimizing two complementary evaluation metrics.Here\, the algorithm and complementary-metrics guaranteed increased strength and diversity\, respectively\, among the ensembles of phalanxes to aggregate. Importantly\, the performances of the two aggregated EPXs are robust against individual EPX when one EPX is good for detecting close homologs and the other is good for detecting distant homologs. Using parallel computing\, the proposed ensemble is shown computationally efficient as well.
