# Test for over/underdispersion

### Description

This function performs a simulation-based test for over/underdispersion

### Usage

1 2 | ```
testOverdispersion(simulationOutput, alternative = "overdispersion",
plot = F)
``` |

### Arguments

`simulationOutput` |
an object with simulated residuals created by |

`alternative` |
whether to test for "overdispersion", "underdispersion", or "both" |

`plot` |
whether to plot output |

### Details

This test compares the approximate deviance (via squared pearson residuals) with the same quantity from a number of simulated models. It is MUCH slower than the parametric alternative `testOverdispersionParametric`

, but potentially more exact in situations where one would expect problems with the chi2 test employed in the parametric test
