WebJun 5, 2001 · The basic idea behind the chi-square goodness of fit test is to divide the range of the data into a number of intervals. Then the number of points that fall into each interval is compared to expected number of points for that interval if the data in fact come from the hypothesized distribution. More formally, the chi-square goodness of fit test ... WebGamma function. by Marco Taboga, PhD. The Gamma function is a generalization of the factorial function to non-integer numbers. It is often used in probability and statistics, as it shows up in the normalizing constants of important probability distributions such as the Chi-square and the Gamma.
