Chi-Square Goodness-of-Fit Test Purpose: Test for distributional adequacy The chi-square test (Snedecor and Cochran, 1989) is used to test if a sample of data came from a population with a specific distribution.
Parametric goodness-of-fit tests assume a specific mathematical form for the candidate distribution, leaving only the values of a few parameters to be tested against the sample.
For each distribution, you can compute the table of expected and observed frequencies and the respective Chi-square goodness-of-fit test, as well as the Kolmogorov-Smirnov d test.
