Ratio Distribution
Given two distributions 
and 
with joint probability density function 
, let 
be the ratio distribution. Then the distribution function of 
is

| (1) |
The probability function is then

For variates with a standard Normal Distribution, the ratio distribution is a Cauchy Distribution. For aUniform Distribution
