statsmodels.genmod.families.links.Link# class statsmodels.genmod.families.links.Link[source]# A generic link function for one-parameter exponential family. Link does nothing, but lays out the methods expected of any subclass. Methods __call__(p) Return the value of the link function. Methods deriv(p) Derivative of the link function g'(p). deriv2(p) Second derivative of the link function g''(p) inverse(z) Inverse of the link function. inverse_deriv(z) Derivative of the inverse link function g^(-1)(z). inverse_deriv2(z) Second derivative of the inverse link function g^(-1)(z).
