This category contains pages concerning Quotient of Gaussian Distributions has Cauchy Distribution:


Let $X$ and $Y$ be independent continuous random variables each with a Gaussian distribution with zero expectation:

\(\ds X\) \(\sim\) \(\ds \Gaussian 0 { {\sigma_x}^2}\)
\(\ds Y\) \(\sim\) \(\ds \Gaussian 0 { {\sigma_y}^2}\)

Let $U$ be the continuous random variable defined as:

$U = \dfrac X Y$


Then $U$ has the Cauchy distribution:

$U \sim \Cauchy 0 \lambda$

where:

$\lambda = \dfrac {\sigma_x} {\sigma_y}$
