VarSelection-Class: class VarSelection

In LinkHD: LinkHD: a versatile framework to explore and integrate heterogeneous data

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

• VarTable dataframe indicating the table that each selected variable comes from.

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