PROC LOGISTIC: The Hosmer-Lemeshow Goodness-of-Fit Test

Webb16 maj 2024 · Many leading researchers in logistic regression do not recommend the Hosmer-Lemeshow test for these reasons. The decile-based calibration curve shares the same drawbacks. Since SAS can easily create the loess-based calibration curve (see the previous article), there seems to be little reason to prefer the decile-based version. Webb16 feb. 2014 · So, the Hosmer-Lemeshow test gives us significant evidence of poor fit on 65% of occasions. That it does not detect the poor fit more often is at least partly a consequence of power - with a larger sample size the power to detect poor fit (or indeed anything!) will be larger.
