OCR: LogLikelihood measures fit and uncertainty in the same manne that sums- -of- -sguares does in interval response situations. The Total -LogLikelihood the negative log likelihood (or uncertainty) when the probabilities are estimated by fixed rates for each response level. This corresponds to the total variation an Analysis of Variance table The Error -LogLikelihood is the uncertainty calculated after fittinc model. This term is found by using separate observed response rates for each sample This value minimized by the log likeliho fitting proc ess The Model -LogLikelihood is the difference between the C Total Error -LogLikelihoods, and it measures the reduction uncertainty due to fitting the model. squares rate
