R: Calculate glsStruct Residuals

residuals.glsStruct {nlme} | R Documentation

## Calculate glsStruct Residuals

### Description

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

### Usage

    ## S3 method for class 'glsStruct'
    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")`.
`...` | some methods for this generic require additional arguments. None are used in this method.

### 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`.
