WebMar 7, 2024 · "The goodness of fit test is a statistical hypothesis test to see how well sample data fit a distribution from a population with a normal distribution. Put differently, this test shows if your sample data represents the data you would expect to find in the actual population or if it is somehow skewed."

The R glm function doesn't report the Nagelkerke-pseudo-" R 2 " but rather the AIC (Akaike Information Criterion).
WebOne of the most widely used goodness of fit tests is the chi-square test. The chi-square test is based on comparing the probability density of the sample data with that of the theoretical distribution. The first step is to divide the sample data into m disjoint sets.
