WebThe Hosmer and Lemeshow Test indicated a good fit (p=.808). Only smoking made a significant contribution (p=.001). Quality of life and total IPPA score were entered in block 2, which was significant (p=.000). The total model was significant (p=.000), and accounted for 34.3 to 45.7 percent of the variance. The model was a good fit. WebApr 16, 2024 · I built a model with 9 categorical predictor variables. Using SPSS, my omnibus test was significant ( χ 2 =220.01), my -2loglikelihood was 1335.2 (Nagelkerke R 2 0.231), but my Hosmer and Lemeshow Test was significant (chi-sqr=16.2, p=0.042). My sample size is n=1199. Is it problematic to proceed with this model, despite lack of fit?
