Dear stata list,
I have an unbalanced sample of 73 firms. When conducting analysis (xtgee), the missing data appears to be a big problem and reduces the total sample down to 34 firms. Should I just note this as a limitation of my analysis or is there something else I could do? I do not really want to change the model I have as the variables in it are theoretically important.
Sorry if this is question is very simple, I am a learner!
Thanks
Alison
