class VarSelection

Description

Class VarSelection S4 class (linkHD: integrating multiple heterogeneous datasets) VarSelection is a class to perform variable selection from a DistStatis object.

Features

  1. class to perform variable selection using Linear Regression Biplot onto the Compromise-Subespace

  2. This method allow variable selection and classification

Fields

  • Variables return all the selected variables (and the frecuency of selection).

  • Coordinates represent the coordenates (Betas coeeficients on LM) of the selected variables.

  • VarTable data.frame indicating which table selected variables come from.

  • values data.frame contains the R2 or pvalue (fdr) of selected variables (it depends of the Crit used).

Accesors
