Description Objects from the Class Slots Extends Methods Author(s) See Also Examples

This class includes the first and second moment estimation result using the multivariate reserving methods in chain ladder. Several primitive methods and statistical methods are also created to facilitate further analysis.

Objects can be created by calls of the form `new("MultiChainLadder", ...)`

, or they could also be a result of calls from `MultiChainLadder`

or `JoinFitMse`

: Method for primitive function`"$"`

. It extracts a slot of`x`

with a specified slot name, just as in list.- [[

. It extracts the i-th slot of a`"MultiChainLadder"`

object, just as in list.`i`

could be a vector.- [[

. It extracts the slots of a`"MultiChainLadder"`

object with names in`i`

, just as in list.`i`

could be a vector.- coef
`signature(object = "MultiChainLadder")`

: Method for function`coef`

, to extract the estimated development matrix. The output is a list.- fitted
`signature(object = "MultiChainLadder")`

: Method for function`fitted`

, to calculate the fitted values in the original triangles. Note that the return value is a list of fitted valued based on the original scale, not the model scale which is first divided by*Y_{i,k}^{δ/2}*.- names
`signature(x = "MultiChainLadder")`

: Method for function`names`

, which returns the slot names of a`"MultiChainLadder"`

object.- plot
`signature(x = "MultiChainLadder", y = "missing")`

: S4 generic function and method to extract residual correlation from a`"MultiChainLadder"`

object.- residuals
`signature(object = "MultiChainLadder")`

: Method for function`residuals`

, to extract residuals from a system of regression equations. These residuals are based on model scale, and will not be equivalent to those on the original scale if*δ*is not set to be 0. One should use`rstandard`

instead, which is independent of the scale.- resid

: Method for`show`

.- summary
`signature(object = "MultiChainLadder")`

: See`summary,MultiChainLadder-method`

.- vcov
`signature(object = "MultiChainLadder")`

: Method for function`vcov`

, to extract the variance-covariance matrix of a`"MultiChainLadder"`

object. Note that the result is a list of`Bcov`

, that is the variance-covariance matrix of the vectorized*B*.
