Screen & Clean

:: DESCRIPTION

Screen & Clean is a program that identifies associations between SNP allele count data and a continuous or binary phenotype. The core function is a screen that identifies the first K SNPs to enter an L1-penalized regression of the phenotype on the allele counts, where K is chosen by a stability criterion. The program includes several optional procedures that are turned off by default, including a pre-screen using marginal regression p-values, a second screen for pairwise interaction effects, and a multivariate regression clean of the screened SNPs. K may also be chosen directly by the user.
