Dear statalist community,

I am using micombine to deal with my missing data. I only have one issue - how do I get an overall model fit statistic with micombine? Is this possible? For instance, I am using:

micombine regress
micombine stcox
micombine logistic
micombine nbreg

Under normal circumstances, I would get an F, r-square, chi-square or some other indicator of overall model fit if I was not using the micombine pre-fix. But, I do not get an F, or chi-square, with micombine. What I have done then is run each of my models separately within each of my 5 imputed datasets using if _j == `num' . . . And, then I thought I could somehow combine the results for an overall chi-square or F. Of course, I am sure I am violating a million rules by averaging these 5 F-values together. Any advice? I just don't want my reviewers, who don't use micombine, to question my results because I don't have the overall fit reported, and I don't want to turn my paper into a statistical treatise (i.e. report all of the results from all 5 models, etcetera, then compare this to the original results), I just want to use micombine as a tool because I don't have room in this paper to expand in this way.

Any advice would be great.
Thanks,
Claire
