Calculates the probability densities, cumulative probabilities, and inverse cumulative probabilities for a chi-square distribution.
Use when random variables are greater than 0. If X has a standard normal distribution, X2 has a chi-square distribution, creating a commonly used sampling distribution. The shape of the chi-square distribution depends on the number of degrees of freedom.
