ABSTRACT<\/strong><\/div>\n

Abstract We consider the problem of building a linear prediction model when the number of candidate covariates is large and the dataset contains a fraction of outliers and other contaminations that are difficult to visualize and clean. We aim at predicting the future non-outlying cases. Therefore, we need methods that are robust and scalable at the same time.<\/p>\n

Our two-step model building procedure consists of\u00a0sequencing<\/em>\u00a0and\u00a0segmentation<\/em>. In\u00a0sequencing<\/em>, we order the covariates and the first m covariates form a reduced set for further consideration. The\u00a0segmentation<\/em>\u00a0step carefully examines subsets of the covariates in the reduced set to select the final prediction model.<\/p>\n

We need a suitable step–by–step algorithm to sequence the covariates. Since Forward Selection (FS) is aggressive, we focus on Least Angle Regression (LARS), a powerful algorithm recently proposed by Efron, Hastie, Johnstone and Tibshirani (2004). We review LARS, and explain one approach to its robustification.<\/p>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
