I am using Stata 13. I have run a logistic regression to check the association of Obesity with several covariates. To assess the fit for the model I ran the Hosmer Lemeshow goodness of fit test and also a ROC curve. For the latter, I ran the Iroc command. This only gives the area under the curve but no p value for it. I would like to know how I can get the 95%CI and significance level for the ROC.
