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 ... http://psych.colorado.edu/~mcclella/psych3101h/StatFinder/oneSampleChiSquare.html

The goodness of fit test consists of testing H 0: β 2 = 0 against the alternative that β 2 is unrestricted. The components of the original parameter vector β are the nuisance parameters for this test. In the generalized linear model
