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

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

Methods

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
