`cors` |
A list of correlation matrices. Must contain rows and columns with |

`nobs` |
A vector with the number of observations per study. |

`Vmats` |
Optional list with 'V' matrices (sampling error variance approximations). |

`Vmethod` |
Which method should be used to apprixomate the sampling error variance? |

`Vestimation` |
How should the sampling error estimates be evaluated? |

`type` |
What to model? Currently only |

`sampleStats` |
An optional sample statistics object. Mostly used internally. |
