OCR: -LogLikelihood for Total Error is the -loglikelihood for the fitted model, the same as the Error line in the Analysis of Loglikelihood report. for Pure Error is the -loglikelihood that would result from fitting separate response probabiliti ies for each sample as distinguished from separate X values. for Lack of Fit is the difference between Total Error and Pure Error -loglikelihoods. ChiSquare twice the -loglikelihood for Lack of Fit, forming likelihood ratio chi -square test for the hypothesis that the model fits as well as the saturated model that fitted response probabilites for each sample combination. Sometimes this is called thGoodness of FitChi-square. Prob> ChiSq the probability of getting an even greater chi-square statistic by chance alone if the hypothesis is true This is also ...
