statsmodels.genmod.families.links.probit

class statsmodels.genmod.families.links.probit(dbn=<scipy.stats._continuous_distns.norm_gen object>)

The probit (standard normal CDF) transform

Notes

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

probit is an alias of CDFLink.

Methods

__call__(p)	CDF link function
deriv(p)	Derivative of CDF link
deriv2(p)	Second derivative of the link function g’‘(p)
inverse(z)	The inverse of the CDF link
inverse_deriv(z)	Derivative of the inverse of the CDF transformation link function
inverse_deriv2(z)	Second derivative of the inverse link function g^(-1)(z).
