ctmaEqual | R Documentation |

test if the two or more invariant drift parameters in the CoTiMAFit object supplied are equal. The supplied CoTiMA fit-object
(ctmaInvariantFit) has to be a model fitted with `ctmaFit`

where at least two parameters were set invariant across primary studies (e.g., 2 cross
effects). All parameters that are set invariant in the supplied model are then constrained to be equal by ctmaEqual (no user action
required), the model is fitted, and a log-liklihood ratio test is performed informing about the probability that equality applies.

```
ctmaEqual(
ctmaInvariantFit = NULL,
activeDirectory = NULL,
activateRPB = FALSE,
digits = 4,
coresToUse = 2
)
```

`ctmaInvariantFit` |
object to which a CoTiMA fit has been assigned to (i.e., what has been returned by |

`activeDirectory` |
defines another active directory than the one used in ctmaInvariantFit |

`activateRPB` |
set to TRUE to receive push messages with CoTiMA notifications on your phone |

`digits` |
Number of digits used for rounding (in outputs) |

`coresToUse` |
If neg., the value is subtracted from available cores, else value = cores to use |

returns a model where two or more parameters were set equal across primary studies and a log-likelihood difference test informing about the probability that the equality assumption is correct.

```
