statsmodels.genmod.families.links.Probit¶

class statsmodels.genmod.families.links.Probit(dbn=<scipy.stats._continuous_distns.norm_gen object>)[source]¶

The probit (standard normal CDF) transform

Methods

__call__(p)

CDF link function

Notes

g(p) = scipy.stats.norm.ppf(p)

probit is an alias of CDFLink.

Methods

deriv(p)	Derivative of CDF link
deriv2(p)	Second derivative of the link function g''(p)
deriv2_numdiff(p)	Second derivative of the link function g''(p)
inverse(z)	The inverse of the CDF link
inverse_deriv(z)	Derivative of the inverse link function
inverse_deriv2(z)	Second derivative of the inverse link function
