statsmodels.genmod.families.varfuncs.Binomial(n=1)[source]¶ Binomial variance function
- Parameters
- n
int,optional The number of trials for a binomial variable. The default is 1 for p in (0,1)
- n
Notes
Formulas :
V(mu) = p * (1 - p) * n
where p = mu / n
Alias for Binomial: binary = Binomial()
A private method _clean trims the data by machine epsilon so that p is in (0,1)
Methods
call
Returns the binomial variance
Methods
deriv(mu)Derivative of the variance function v’(mu)
