Troubleshooting
Problem
I'm running logistic regression models with binary response data in SPSS, and am requesting the Hosmer-Lemeshow goodness-of-fit test. I've discovered that in some situations, the results of the HL test depend upon which category of the dependent variable is chosen as the target category. That is, if I reverse a 0-1 or recode the 0 values to 2, so that the logits are formed differently, transforming my predicted probabilities from p to 1-p, the HL chi-square and significance can be different. Is this a bug in SPSS?
