statsmodels.genmod.families.links.Link.inverse_deriv

Link.inverse_deriv(z) [source]

Derivative of the inverse link function g^(-1)(z).

Parameters: z (array-like) – z is usually the linear predictor for a GLM or GEE model.
Returns: g’^(-1)(z) – The value of the derivative of the inverse of the link function
Return type: array

Notes

This reference implementation gives the correct result but is inefficient, so it can be overriden in subclasses.
