ChiDist(X, DegreesOfFreedom)
X. The value, for which the distribution must be calculated. The value must satisfy the constraint: X >= 0.
DegreesOfFreedom. Number of degrees of freedom. Available values are taken from the range (1, 10^10).
The method returns the one-tailed probability of the chi-squared distribution.
The χ2 distribution is related to the χ2 criterion. The χ2 criterion is used to compare observed and expected values.
The value is calculated by formula:
ChiDist = P(X>x),
where:
