ChiSquarePValue

ChiSquarePValue[x, df]
gives the cumulative probability beyond x for the

² distribution with df degrees of freedom.

MORE INFORMATION

To use ChiSquarePValue, you first need to load the Hypothesis Testing Package using Needs["HypothesisTesting`"].

The one-sided p-value is CDF[ChiSquareDistribution[df], x] if x is less than the median of the ² distribution with df degrees of freedom, and 1-CDF[ChiSquareDistribution[df], x] otherwise.

The two-sided p-value is twice the one-sided p-value.

The following options can be given:

whether to perform a two-sided test
