loglik.mix {mix}

Loglikelihood for Incomplete Data under the General Location Model

Description

Calculates the observed-data loglikelihood under the general location model at a user-specified parameter value.

Usage

loglik.mix(s, theta)

Arguments

s

summary list of an incomplete data matrix x created by the function prelim.mix.

theta

parameter list, such as one produced by ecm.mix or da.mix.

Value

the value of the loglikelihood function at theta.
