Calculate the residuals of a model after removing the effect of the first ncomp components.
This function is useful to assess the quality of the fit or to identify patterns that are not
captured by the model.
Usage
residuals(x, ncomp, xorig, ...)
Arguments
- x
The model fit object.
- ncomp
The number of components to factor out before calculating residuals.
- xorig
The original data matrix (X) used to fit the model.
- ...
Additional arguments passed to the method.
Value
A matrix of residuals, with the same dimensions as the original data matrix.
