Marginal screening
WebA different screening procedure is recently proposed by Wang & Leng (2016), which aims to target joint associations in a covariate space in the dimension of the sample size. 1.2 False negatives in marginal screening Naturally, the success of any marginal screening procedure depends on how well the marginal utility, correlation WebAbstract. We develop a framework for post model selection inference, via marginal screening, in linear regression. At the core of this framework is a result that characterizes the exact distribution of linear functions of the response y y, conditional on the model being selected ( condition on selection framework). This allows us to construct ...

Moreover, in contrast with most screening methods that usually employ subjective thresholds for screening, we also WebDec 1, 2024 · The hard thresholding rule, widely adopted in screening methods, selects covariates with the d = n/ log n largest marginal dependence measures, where n is the sample size (Fan and Lv, 2008).
WebSecondly, conditional screening helps for reducing the number of false negatives. Marginal screening can fail when there are covariates in the non-active set that are highly correlated with active variables.
