Update any internal structures associated with sqrtXwt and the
weighted residuals. The "V" matrix is evaluated from X using the
sqrtXwt matrix and a Vtr vector is calculated.
Usage
reweightPred(predM, sqrtXwt, wtres, ...)
Arguments
predM
a predictor module
sqrtXwt
the sqrtXwt matrix
wtres
the vector of weighted residuals
