Penalized multivariate analysis
WebNov 20, 2024 · Background Penalised regression methods are a useful atheoretical approach for both developing predictive models and selecting key indicators within an often substantially larger pool of available indicators. In comparison to traditional methods, penalised regression models improve prediction in new data by shrinking the size of … WebArguably, the goal of a regression analysis is to “build” a ... Hence, penalized estimation with this penalty is equivalent to using the MAP (Maximum A Posteriori) estimator of with a Gaussian prior. ... This should lead to “multivariate” shrinkage of the vector .

WebMar 1, 2024 · Abstract. Functional data analysis is a fast evolving branch of statistics, but estimation procedures for the popular functional linear model either suffer from lack of robustness or are computationally burdensome. To address these shortcomings, a flexible family of penalized lower-rank estimators based on a bounded loss function is proposed.
