Limits the number of models for which fit measures will be retained and reported. For example, if you specify Retain only the best 10 models, the next specification search will retain and report fit measures for no more than 10 1-parameter models, no more than 10 2- parameter models, and so on. To remove any limitation on the number of models reported, specify Retain only the best 0 models.

Limiting the number of models reported can speed up a specification search significantly. At the present writing, it is not practical to retain and report fit measures for more than about 4000 models, although the number of models fitted during a specification search can be much larger than that.

Specifying a non-zero value for Retain only the best ___ models prevents the program from normalizing Akaike weights and Bayes factors so that they sum to one across all models.
