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
deriv(p) Derivative of CDF link
deriv2(p) Second derivative of the Cauchy link function.
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).
