- ChiSquared( <Degrees of Freedom>, x )
- Creates cumulative density function (cdf) of Chi squared distribution with the appropriate degrees of freedom.
- ChiSquared( <Degrees of Freedom>, x, <Boolean Cumulative> )
- If the logical value is true, creates cumulative distribution function of Chi squared distribution, otherwise creates pdf of Chi squared distribution.
- ChiSquared( <Degrees of Freedom>, <Variable Value> )
- Calculates the value of cumulative distribution function of Chi squared distribution at Variable Value v, i.e. the probability P(X ≤ v) where X is a random variable with Chi squared distribution with the appropriate degrees of freedom.
- Note: Returns the probability for a given x-coordinate's value (or area under the Chi squared distribution curve to the left of the given x-coordinate).
- Example:
ChiSquared(4, 3)yields \gamma(2, \frac{3}{2}), which is approximately 0.44.
