These functions give you access to the Cauchy distribution. For more information about Fathom's distribution functions, click here.

distribution |
The density, cumulative, and quantile functions for the Cauchy distribution. Only the x (the independent variable) is required. If you supply scale, it must be positive. defaults: mode = 0, scale = 1. |
You may also draw random values from this distribution:
randomCauchy(mode, scale) |
A random value drawn from that distribution. |
Here are some plots to help you understand the meaning of the parameters. The Cauchy is like the normal distribution in that it is a hump that depends only on a center (mode) and a spread (scale).
