"MultiChainLadderFit" is a virtual class for the fitted models in the multivariate chain ladder reserving framework, "MCLFit" is a result from the interal call `.FitMCL`

to store results in model `MCL`

and "GMCLFit" is a result from the interal call `.FitGMCL`

to store results in model `GMCL`

. The two classes "MCLFit" and "GMCLFit" differ only in the presentation of *B_k* and *Σ_{B_k}*, and different methods of `Mse`

and `predict`

will be dispatched according to these classes.

"MultiChainLadderFit" is a virtual Class: No objects may be created from it. For "MCLFit" and "GMCLFit", objects can be created by calls of the form `new("MCLFit", ...)`

and `new("GMCLFit", ...)`

respectively.

"MCLFit" and "GMCLFit" extends class `"MultiChainLadderFit"`

, directly.

No methods defined with class "MultiChainLadderFit" in the signature.

For "MCLFit", the following methods are defined:

`Mse`

`signature(ModelFit = "MCLFit", FullTriangles = "triangles")`

: Calculate Mse estimations.`predict`

`signature(object = "MCLFit")`

: Predict ultimate losses and complete the triangles. The output is an object of class "triangles".

For "GMCLFit", the following methods are defined:

`Mse`

`signature(ModelFit = "GMCLFit", FullTriangles = "triangles")`

: Calculate Mse estimations.`predict`

`signature(object = "GMCLFit")`

: Predict ultimate losses and complete the triangles. The output is an object of class "triangles".
