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').
