statsmodels.genmod.families.family.Family

class statsmodels.genmod.families.family.Family(link, variance)

The parent class for one-parameter exponential families.

Parameters:

link : a link function instance

Link is the linear transformation function. See the individual families for available links.

variance : a variance function

Measures the variance as a function of the mean probabilities. See the individual families for the default variance function.
