    statsmodels.genmod.families.links.CDFLink¶

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

    The use the CDF of a scipy.stats distribution

    CDFLink is a subclass of logit in order to use its _clean method for the link and its derivative.

    Parameters
    dbnscipy.stats distribution

    Default is dbn=scipy.stats.norm

    Notes

    The CDF link is untested.

    Methods

    __call__(p)

    CDF link function

    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 g^(-1)(z).
