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

deriv(p)	Derivative of log transform link function
deriv2(p)	Second derivative of the link function g??(p)
inverse(z)	Inverse of log transform link function
inverse_deriv(z)	Derivative of the inverse of the log transform link function
