testSTACD | R Documentation |

Tests if the alpha parameters and the constant should be varying with the value of the lagged durations, according to a logistic transition function.

```
testSTACD(fitModel, K = 2, robust = TRUE)
```

`fitModel` |
a fitted ACD model, i.e. an object of class "acdFit". |

`K` |
the order of the logistic transition function used for the alternative hypothesis. |

`robust` |
if |

a list of:

`chi2` |
the value of the LM statistic. |

`pv` |
the pvalue of the test statistic. |

`testRmACD`

, `testTVACD`

.

```
fitModel3000obs <- acdFit(adjDurData[1:3000,])
testSTACD(fitModel3000obs, K = 2, robust = TRUE)
```
