WebHosmer and Lemeshow (1980) method is as follows: Order the observations based on their estimated probabilities Partition ordered observations into 10 groups ( g = 10) by either of … WebThe Hosmer-Lemeshow test is performed by dividing the predicted probabilities into deciles (10 groups based on percentile ranks) and then computing a Pearson chi-square that compares the predicted to the observed frequencies (in a 2 × 10 table). Lower values (and nonsignificance) indicate a good fit to the data and, therefore, good overall model
