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

The density, cumulative, and quantile functions for the chi-square distribution. The df parameter is required and must be >= 1. The scale parameter accounts for multiplicative scaling of the statistic, maintaining the unit area under the density curve. The min parameter simply translates the density function. defaults: scale = 1, min = 0. Most uses never need to change these. |
You may also draw random values from this distribution:

These plots show how the df parameter controls the shape of the curve.
