    statsmodels.genmod.families.links.cauchy¶

    class statsmodels.genmod.families.links.cauchy[source]¶

    The Cauchy (standard Cauchy CDF) transform

    Notes

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

    cauchy is an alias of CDFLink with dbn=scipy.stats.cauchy

    Methods

    __call__(p)

    CDF link function

    Methods

    deriv(p)

    Derivative of CDF link

    deriv2(p)

    Second derivative of the Cauchy link function.

    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).
