AddBinVars2Biplot function

Add suplementary binary variables to a biplot

Add suplementary binary variables to a biplot of any kind

AddBinVars2Biplot(bip, Y, IncludeConst = TRUE, penalization = 0.2, 
freq = NULL, tolerance = 1e-05, maxiter = 100)

Arguments

• bip: A biplot object
• Y: Matrix of binary variables to add
• IncludeConst: Should include a constant in the fit
• penalization: Penalization for the fit
• freq: frequencies for each row of Y. By default is 1.
• tolerance: Tolerance for the fit
• maxiter: Maximum number of iterations

Details

Fits binary variables to an existing biplot using penalized logistic regression.

Returns

The biplot object with supplementary binary variables added.
