Global goodness-of-fit
WebThe other approach to evaluating model fit is to compute a goodness-of-fit statistic. With PROC LOGISTIC, you can get the deviance, the Pearson chi-square, or the Hosmer-Lemeshow test. These are formal tests of the null hypothesis that the fitted model is correct, and their output is a p-value--again a number between 0 and 1 with higher WebNov 30, 2007 · 2.3 Goodness-of-fit statistic (GFI) and the adjusted goodness-of-fit statistic (AGFI) The Goodness-of-Fit statist ic (GFI) was created by Jö re skog and Sorbom as …
