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

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.

Arguments

object

an object of class "mixmeta".

format

format of the returned object.

...

further arguments passed to or from other methods.
