logLik.rma: Log-Likelihood of rma Objects

Description

The function extracts the (restricted) log likelihood for objects of class "rma".

Usage

## S3 method for class 'rma':
logLik(object, REML, \dots)

Arguments

object

an object of class "rma".

REML

an optional logical value. If TRUE, the restricted log-likelihood is returned, else, if FALSE, the log-likelihood is returned. Defaults to the method of estimation used, that is TRUE if object was fitted

...

other arguments.

Value

• An object of class "logLik". The object provides the (restricted) log likelihood of the model evaluated at the estimated coefficient(s).
