coef.mixmeta {mixmeta}

Extract Coefficients and (Co)Variance Matrix from mixmeta Objects

Description

These method functions return the estimated fixed-effects coefficients and their (co)variance matrix for fitted meta-analytical models represented in objects of class "mixmeta".

Usage

## S3 method for class 'mixmeta'
coef(object, format=c("vector","matrix"), ...)

## S3 method for class 'mixmeta'
vcov(object, ...)

Arguments

object

an object of class "mixmeta".

format

format of the returned object.

...

further arguments passed to or from other methods.

Value

For coef, by default a vector (default)with the estimated fixed-effects coefficients. For multivariate models, a matrix can also be returned.

For vcov, the (co)variance matrix of the estimated fixed-effects coefficients.
