Web2.4 - Goodness-of-Fit Test. A 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 ...
