Extracting different types of residuals from a `Mort2Dsmooth`

object.

`object` |
An object of class "Mort2Dsmooth", usually, a result of
a call to |

`type` |
The type of residuals which should be returned. The alternatives are: "deviance" (default), "anscombe", "pearson" and "working". |

`...` |
Further arguments passed to or from other methods. Not in used. Not in use. |

The references define the types of residuals.

The way of computing the residuals are described in Section 2.4 of McCullagh and Nelder's book. The working residuals are merely the differences between fitted and actual counts.

A matrix of the selected type of residuals over both the `x`

and
the `y`

axes in the `Mort2Dsmooth`

object.
