Package: BioMark 0.4.5
BioMark: Find Biomarkers in Two-Class Discrimination Problems
Variable selection methods are provided for several classification methods: the lasso/elastic net, PCLDA, PLSDA, and several t-tests. Two approaches for selecting cutoffs can be used, one based on the stability of model coefficients under perturbation, and the other on higher criticism.
