The `weights.meta`

method returns a data frame containing
information on absolute and percentage weights of individual studies
contributing to fixed effect and random effects meta-analysis.

1 2 3 |

`object` |
An object of class |

`comb.fixed` |
A logical indicating whether absolute and percentage weights from the fixed effect model should be calculated. |

`comb.random` |
A logical indicating whether absolute and percentage weights from the random effects model should be calculated. |

`...` |
Additional arguments (ignored at the moment). |

A data frame with the following variables is returned:

Variable | Definition | Condition |

w.fixed | absolute weights in fixed effect model | (if `comb.fixed = TRUE` ) |

p.fixed | percentage weights in fixed effect model | (if `comb.fixed = TRUE` ) |

w.random | absolute weights in random effects model | (if `comb.random = TRUE` ) |

p.random | percentage weights in random effects model | (if `comb.random = TRUE` ) |
