WebThe Hosmer-Lemeshow goodness-of-fit statistic is computed as the Pearson chi-square from the contingency table of observed frequencies and expected frequencies. Similar to a test of association of a two-way table, a good fit as measured by Hosmer and Lemeshow’s test will yield a large p-value. Webvalidation Index (ECVI), the root mean square residual (RMR), and the standardized root mean square residual (SRMR). Most of these indices, with the possible exception of the SRMR, have similar problems to those of the chi-square, because they are simple transformationsof chi-square. As one example, the AIC (as given by Tanaka, 1993) is …

WebThe cells with the largest residuals might contribute the most to the chi-square statistic. However cells with larger cell counts will also have larger residuals. To make the residuals more comparable, they are standardized by dividing by √𝐸 . The 𝑟 above represent the standardized residuals, also called the Pearson residuals.
