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 ... WebAs you can see, the studentized residual (" TRES1 ") for the red data point is t4 = -19.7990. Now we just have to decide if this is large enough to deem the data point influential. To do that we rely on the fact that, in general, studentized residuals follow a t distribution with ( n – k –2) degrees of freedom. centos check cpu speed https://azambujaadvogados.com
