However, the H–L test is sensitive to … WebThe Hosmer–Lemeshow test is then calculated as C 1 g = ˘ h=0 ˘g d=1{(Ohd −Ehd) 2/E hd}. This quantity is distributed as χ2 g−2 when K = n (Hosmer and Lemeshow 1980). When fitting logistic regression models using survey data, the sampling weight, wji, calculated as the inverse of the product of the conditional inclusion probabilities ...
