Residuals of a Generalised Linear Model for Time Series of Counts

Description

Returns the residuals of a fitted GLM-type model for time series of counts.

Usage

1
2
## S3 method for class 'tsglm'
residuals(object, type = c("response", "pearson", "anscombe"), ...)

Arguments

object

an object of class "tsglm". Usually the result of a call to tsglm.

type

character value giving the type of residuals which should be returned. Choose type="response" for raw residuals, type="pearson" for Pearson residuals and type="anscombe" for Anscombe residuals.

...

further arguments are currently ignored. Only for compatibility with generic function.

Details

Computes a vector with the respective residuals of the fit given in argument object.

Value

Numerical vector of the residuals.
