Snedecor Law 

The Snedecor law is parameterized by two non-dimensional numbers and .
 
  Let's take a random variable following the Snedecor law of parameters and ,
then can be expressed in terms of two random variables ,
following Pearson law respectively of parameter , as:
 

is distributed according to the following density of probability, where:

 

With mean:

 

With variance:

 

With standard deviation:
