``smoothing``
-------------

- Available in: Target Encoding

Description
~~~~~~~~~~~

The smoothing value is used for blending and to calculate ``lambda``. Smoothing controls the rate of transition between the particular level's posterior probability and the prior probability. For smoothing values approaching infinity, it becomes a hard threshold between the posterior and the prior probability. This value defaults to 20.
