Marginal screening

WebFeb 23, 2014 · Although we focus on marginal screening to illustrate the applicability of the condition on selection framework, this framework is much more broadly applicable. We show how to apply the proposed framework to several other selection procedures including orthogonal matching pursuit, non-negative least squares, and marginal screening+Lasso. WebThis directory contains an MCMC sampler that provides Bayesian selective inference, that is based on a selection-adjusted posterior. The methods include implementation of inference (credible intervals and selection-adjusted MAP) post LASSO, forward stepwise regression, marginal screening, multi-stage screening algorithms.
