residuals {multivarious}

Obtain residuals of a component model fit

Description

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.
