coefs.plsRnp: Coefficients for bootstrap computations of PLSR models

In plsRglm: Partial Least Squares Regression for Generalized Linear Models

Coefficients for bootstrap computations of PLSR models

Description

A function passed to boot to perform bootstrap.

Usage

coefs.plsRnp(dataRepYtt, ind, nt, modele, maxcoefvalues, wwetoile, ifbootfail)

Arguments

dataRepYtt	components' coordinates to bootstrap
ind	indices for resampling
nt	number of components to use
modele	type of modele to use, see plsRglm
maxcoefvalues	maximum values allowed for the estimates of the coefficients to discard those coming from singular bootstrap samples
wwetoile	values of the Wstar matrix in the original fit
ifbootfail	value to return if the estimation fails on a bootstrap sample

Value

estimates on a bootstrap sample or ifbootfail value if the bootstrap computation fails.
