Unformatted text preview: N mode Calculate E2 for however many column categories you have: E2 = [N (category total) N (category mode) ] + [N (category total) N (category mode) ] etc Lambda = [E1 E2] / E1 CALCULATING GAMMA This is a symmetrical measure of association for ordinal or dichotomous nominal variables. Be sure table is arranged in rank order across and down First count the number of same order pairs (N s ) (ie: HIGH/HIGH or LOW/LOW) Count number of inverse order pairs (N d ) (ie : HIGH/LOW or LOW/HIGH) Ns=(total high/high )*(total low/low ) See page 378 in your book Nd=(total high/low)*(total low/high ) also page 378 The result is read as the proportional reduction of error 1 2 1 E E E PRE 1 2 1 E E E Lambda categories all for category for e category N N E ) ( 2 mod Nd Ns Nd Ns Gamma...
