Bootstrap (Y,T) function for PLSGLR

A function passed to boot to perform bootstrap.

Usage

coefs.plsRglm.CSim(
  dataRepYtt,
  ind,
  nt,
  modele,
  family = NULL,
  maxcoefvalues,
  ifbootfail
)

Arguments

dataRepYtt

Dataset with tt components to resample

ind

indices for resampling

nt

number of components to use

modele

type of modele to use, see plsRglm. Not used, please specify the family instead.

family

glm family to use, see plsRglm

maxcoefvalues

maximum values allowed for the estimates of the coefficients to discard those coming from singular bootstrap samples

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.

Numeric vector of the components computed using a bootstrap resampling.
