- class statsmodels.genmod.families.links.Log[source]#
The log transform
Methods
__call__(p, **extra)Log transform link function
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
Derivative of the inverse of the log transform link function
Second derivative of the inverse link function g^(-1)(z).
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.
