This function provides the (restricted) log-likelihood of a fitted model.
Usage
# S3 method for class 'riley'
logLik(object, ...)
Arguments
- object
A riley object, representing a fitted alternative model for bivariate random-effects
meta-analysis when the within-study correlations are unknown.
- ...
Additional arguments to be passed on to other functions, currently ignored.
Value
Returns an object of class logLik. This is the (restricted) log-likelihood of the model represented
by object evaluated at the estimated coefficients. It contains at least one attribute,
"df" (degrees of freedom), giving the number of (estimated) parameters in the model.
