, commonly returned by gw
function. Optionally, it produces a normal plot with a simulated envelope of the residuals.

type of residuals to be extracted. Default is |

number of replications for envelope construction. Default is 19, that is the smallest 95 percent band that can be built. |

a title for the envelope. |

The usual Q-Q plot may show an unsatisfactory pattern of the residuals of a model fitted: then we are led to think that the model is badly specificated. The normal plot with simulated envelope indicates that under the distribution of the response variable the model is OK if only a few points fall off the envelope.
