Hi all,

I have a propotion dependent variable that’s greater than zero and less then one. The mean is 0.1240891 and SD 0.1363 and its positivly skewed. All the independent variables are dummy variables. I have read that betareg is most appropriate model for propotion data.
Want to check did I use the right model and also do I need to check any assumptions before carrying betareg ?

Betareg dep i.var1 i.var2 i.var3 i.var4
margins dep

After running estat ic to check the model fit AIC and BIC are approx -4400

Thank you in advance.
