What is the command for specifying the denominator when fitting a binomial or multinomial model?
The command is DOFFs. For documentation see p88 of the MLwiN version 2.10 Beta manual supplement. Note that although the documentation for the command is in the manual supplement for version 2.10, this command does also work in version 2.02, as do most of the other commands documented under the heading ‘Other useful commands for specifying discrete response models in macros’.
