st: Model goodness-of-fit
Dear List members,
I have two continuous variables and eight dummy variables in a logistic
regression model (n= about 17,500). I tried to test the model goodness of
fit with Hosmer Lemeshow test which gave me large chi2 value with very small
p value, showing the lack of fit. If I drop one of the two continuous
variables from the model, I get much smaller Chi2 with large p values. Since
this is the most important variable I would like have in the model, I would
appreciate receiving your suggestion as to how I could solve this problem.
Is there any other tests available in Stata? Surprisingly, while searching
the net I came across a very big criticism of using Hosmer-Lemeshow test.
