mvmeta (version 1.0.3)

coef.mvmeta: Extract Coefficients and (Co)Variance Matrix from mvmeta Objects

Description

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

Usage

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

Arguments

object

an object of class "mvmeta".

format

format of the returned object.

…

further arguments passed to or from other methods.

Value

For coef, a vector (default) or matrix with the estimated fixed-effects coefficients. The matrix-structure is used to store the fixed-effects coefficients in mvmeta objects, and is preserved if format="matrix".

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