Calculate glsStruct Residuals

Description

The residuals for the linear model represented by object are extracted.

Usage

residuals(object, glsFit)

Arguments

object an object inheriting from class glsStruct, representing a list of linear model components, such as corStruct and varFunc objects.
glsFit an optional list with components logLik (log-likelihood), beta (coefficients), sigma (standard deviation for error term), varBeta (coefficients' covariance matrix), fitted (fitted values), and residuals (residuals). Defaults to attr(object, "glsFit").

Value

a vector with the residuals for the linear model represented by object.

Note

This method function is primarily used inside gls and residuals.gls.
