## Plot method for a MunichChainLadder object

### Description

`plot.MunichChainLadder`

, a method to plot the output of
`MunichChainLadder`

object. It is designed to give a quick
overview of a `MunichChainLadder`

object and to check the
correlation between the paid and incurred residuals.

### Usage

```
## S3 method for class 'MunichChainLadder'
plot(x, mfrow=c(2,2), title=NULL, ...)
```

### Arguments

`x` |
output from |

`mfrow` |
see |

`title` |
see |

`...` |
optional arguments. See |

### Details

`plot.MunichChainLadder`

shows four plots, starting from the top
left with a barchart of forecasted ultimate claims costs by
Munich-chain-ladder (MCL) on paid and incurred data by origin period;
the barchart next to it compares the ratio of forecasted ultimate
claims cost on paid and incurred data based on the Mack-chain-ladder and
Munich-chain-ladder methods; the two residual plots at the bottom show the
correlation of (incurred/paid)-chain-ladder factors against the
paid-chain-ladder factors and the correlation of
(paid/incurred)-chain-ladder factors against the incurred-chain-ladder
factors.

### Note

The design of the plots follows those in Quarg's (2004) paper: Gerhard Quarg and Thomas Mack. Munich Chain Ladder. Blatter DGVFM 26, Munich, 2004.
