SparseBiplots

CRAN status

Overview

Sparse Biplots are modern variant of HJ-Biplot which attempts to find sparse loadings, i.e., weight vectors with only a few nonzero values. Introducing a penalty parameter helps improve the interpretation of the model because the axis are formed as a linear combination of only some of the original variables.

This package provides functions to perform the HJ-Biplot (Galindo, 1986) and modifications introducing Ridge, LASSO and Elastic Net penalty:

Example

{r Fit HJ-Biplot} library("SparseBiplots") hj.biplot <- HJBiplot(mtcars) It fit the HJ-Biplot on the R data mtcars returning a list that contains the results of the fiting (hj_mtcars). To create the plot use the function Plot_Biplot over the list obtained.

{r Visualize HJ-Biplot} Plot_Biplot(hj.biplot, ind.label = TRUE)
