statsmodels.genmod.families.family.Binomial(link=<class 'statsmodels.genmod.families.links.logit'>)[source]¶ Binomial exponential family distribution.
Parameters: link : a link instance, optional
The default link for the Binomial family is the logit link. Available links are logit, probit, cauchy, log, and cloglog. See statsmodels.family.links for more information.
Notes
endog for Binomial can be specified in one of three ways.
