Log-Likelihood of an eba Object — logLik.eba • eba

Returns the log-likelihood value of the (multi-attribute) probabilistic choice model represented by object evaluated at the estimated parameters.

Arguments

object: an object inheriting from class eba, representing a fitted elimination-by-aspects model
...: some methods for this generic require additional arguments; none are used in this method.
