Description

Takes in a set of predictor variables and a set of response variables and produces a zoomed-in display of the coefficient points in the PLS biplot for the (univariate) GLMs.

Usage

1
PLS.GLM.biplot_bvec(X, y, algorithm = NULL, ax.tickvec.b = NULL, ...)

Arguments

X

A (NxP) predictor matrix

y

A (Nx1) response vector

algorithm

The PLS.GLM_SIMPLS algorithm

ax.tickvec.b

(purple) tick marker length for the y-variable axis in the biplot

...

Other arguments. Currently ignored

Value
