`weights.rma.Rd`

The function computes the weights given to the observed effects or outcomes during the model fitting for objects of class `"rma.uni"`

, `"rma.mh"`

, `"rma.peto"`

, and `"rma.mv"`

.

# S3 method for rma.uni weights(object, type="diagonal", ...) # S3 method for rma.mh weights(object, type="diagonal", ...) # S3 method for rma.peto weights(object, type="diagonal", ...) # S3 method for rma.glmm weights(object, ...) # S3 method for rma.mv weights(object, type="diagonal", ...)

object | an object of class |
---|---|

type | character string indicating whether to return only the diagonal of the weight matrix ( |

... | other arguments. |

Either a vector with the diagonal elements of the weight matrix or the entire weight matrix. When only the diagonal elements are returned, they are given in % (and they add up to 100\% \times). When the entire weight matrix is requested, this is always a diagonal matrix for objects of class `"rma.uni"`

, `"rma.mh"`

, `"rma.peto"`
