countregFitModel - What types of count data models can be fitted with this action?
Réponse
The action can fit several model types via the 'modeltype' parameter. Supported models include Poisson ('POISSON'), Negative Binomial (type 1 and 2: 'NEGBIN1', 'NEGBIN2'), and Conway-Maxwell-Poisson ('CMPOISSON'). It also handles zero-inflated variations like Zero-Inflated Poisson ('ZIP'), Zero-Inflated Negative Binomial ('ZINB'), and Zero-Inflated Conway-Maxwell-Poisson ('ZICMPOISSON').
