Problem Note 36805: Incorrect full log likelihood, AIC, and BIC statistics with events/trials data and FREQ statement
 |  |  |  |
When the FREQ statement is specified with events/trials syntax in the MODEL statement, the full log likelihood, AIC, AICC, and BIC statistics are incorrect in the "Criteria For Assessing Goodness Of Fit" table. The frequency counts are not properly accounted for in the combinatorial term of the binomial log likelihood. However, the model is fit properly and all other statistics are correct.
There is no circumvention for this problem.
