For a (k x k) square contingency table with ordered categories, let X (Y) denote the row (column) number. The conditional symmetry model is given by P(X=i,Y=j|X<Y)=P(X=j,Y=i|X>Y), for all ij. In this paper, we study the likelihood ratio tests of conditional symmetry in a square contingency table against two...</y)=p(x=j,y=i|x>
