WebApr 29, 2024 · The goodness-of-Fit test is a handy approach to arrive at a statistical decision about the data distribution. It can be applied for any kind of distribution and … WebA goodness-of-fit test, in general, refers to measuring how well do the observed data correspond to the fitted (assumed) model. We will use this concept throughout the course as a way of checking the model fit. Like in linear regression, in essence, the goodness-of-fit test compares the observed values to the expected (fitted or predicted) values.
