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

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).
