coef.mixmeta function

Extract Coefficients and (Co)Variance Matrix from mixmeta Objects

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".

## 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.

Returns

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.
