class statsmodels.genmod.families.links.Log[source]

The log transform

Notes

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

Methods

__call__(p, **extra)

Log transform link function

Methods

deriv(p)

Derivative of log transform link function

deriv2(p)

Second derivative of the log transform link function

inverse(z)

Inverse of log transform link function

inverse_deriv(z)

Derivative of the inverse of the log transform link function

inverse_deriv2(z)

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