Hi everyone,
I have a continues, all positive outcome (CTDI) and it is skewed. I checked ln(CTDI) which is still not normal. I'm not sure which of the following options is the correct one.
1- xtgee CTDI var1 var2, corr(independent) (I've used this option because I know that GEE approach forgoes the distribution assumption, providing valid inference regardless of the distribution of the data.)
2-xtgee ln_CTDI var1 var2, corr(independent) efom (I ran this model and got very different results from option 1)
3-xtgee CTDI var1 var2, family(gamma) link(log) corr(independent)
Regards,
