Log-likelihood of an Rceattle fit — logLik.Rceattle • Rceattle

Returns the joint negative-objective from nlminb, sign-flipped, as a "logLik" object. df is the number of estimated fixed-effect parameters. The nobs attribute is intentionally omitted: counting "observations" in a stock assessment likelihood (with composition cells, indices, catches, and priors) is not well-defined, so stats::AIC() works (uses df) while stats::BIC() does not.

Usage

# S3 method for class 'Rceattle'
logLik(object, ...)

Arguments

object: An object of class "Rceattle" returned by fit_mod().
...: Currently unused.

Value

An object of class "logLik", or NULL if the model was not estimated.
