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

The log-complement transform

Methods

__call__(p, **extra)

Log-complement transform link function

Notes

call and derivative call a private method _clean to trim the data by machine epsilon so that p is in (0,1). logc is an alias of LogC.

Methods

deriv(p)	Derivative of log-complement transform link function
deriv2(p)	Second derivative of the log-complement transform link function
inverse(z)	Inverse of log-complement transform link function
inverse_deriv(z)	Derivative of the inverse of the log-complement transform link function
inverse_deriv2(z)	Second derivative of the inverse link function g^(-1)(z).
