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

Probability density function for a chi-square distribution.

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

\[\operatorname {pdf}(x)=\dfrac {x^{\frac {k}{2}-1}e^{-\frac {x}{2}}} {2^\frac {k}{2}\Gamma \left(\frac {k}{2}\right)}\]

where \(\Gamma\) is the gamma function.

Parameters:
  • point (VariableMeasureConvertible) – The point where the function is evaluated.

  • degrees_of_freedom (StrictlyPositiveNumber | VariableMeasureConvertible) – The number of degrees of freedom. Must be positive.

Return type:
