In TIMP: Fitting Separable Nonlinear Models in Spectroscopy and Microscopy

For data correction, fits a model (but ignores plotting commands) in order to obtain the SVD of the residuals, which then can be used in data-correction.

Description

For data correction, fits a model exactly as does fitModel (but ignores plotting commands) in order to obtain the SVD of the residuals. These residuals can then be subtracted away from the original data to some extent with the preProcess function.

Usage

getResid(data, modspec=list(), datasetind = vector(),
     modeldiffs = list(), opt = opt() )

Arguments

data	As in the fitModel function
modspec	As in the fitModel function
datasetind	As in the fitModel function
modeldiffs	As in the fitModel function
opt	As in the fitModel function

Value

list containing the first five left and right singular vectors of the residuals, as well as the first five singular values. A weight matrix (if used) is also included in this list.
