Fitting the Parametric Bayesian Model of Ecological Inference in 2x2 Tables

Description

Qfun returns the complete log-likelihood that is used to calculate the fraction of missing information.

Usage

Qfun(theta, suff.stat, n)

Arguments

theta	A vector that contains the MLE E(W_1),E(W_2), var(W_1),var(W_2), and cov(W_1,W_2). Typically it is the element theta.em of an object of class ecoML.
suff.stat	A vector of sufficient statistics of E(W_1), E(W_2), var(W_1),var(W_2), and cov(W_1,W_2).
n	A integer representing the sample size.

Value

A single numeric value: the complete-data log-likelihood.
