Usage

## S3 method for class 'rma':
logLik(object, REML=NULL, ...)

Arguments

object

an object of class "rma".

REML

logical indicating whether the regular or restricted log likelihood should be returned. When NULL (default), the regular log likelihood is returned, unless restricted maximum likelihood estimation was used to fit the model.
