atoti.experimental.stats.chi2.cdf(point, /, *, degrees_of_freedom)

Cumulative distribution function for a chi-square distribution.

The cdf of the chi-square distribution with k degrees of freedom is

\[\operatorname {cdf}(x)=\dfrac {\gamma (\frac {k}{2},\,\frac {x}{2})}{\Gamma (\frac {k}{2})}\]

where \(\Gamma\) is the gamma function and \(\gamma\) the lower incomplete gamma function.

Parameters:

• point (NonConstantMeasureConvertible) – The point where the function is evaluated.

• degrees_of_freedom (int | float | NonConstantMeasureConvertible) – The number of degrees of freedom. Must be positive.

Return type:
