Consider the loglinear model of conditional independence between A and B, given C, in a r × c × ???? contingency table. Derive the likelihood equations, and interpret. Give the solution of fitted values that satisfies the model and the equations. (From Birch (1963), it follows that only one solution exists, namely the ML fit.) Explain the connection with the fitted values for the independence model for a two-way table. Find the residual df for testing fit.
