Dear all,

I am running regression
(e.g. OLS). Let's say I have trade of 20 countries with 5 states over 15
years period. Assuming that there are no missing data, I will have (20*5
cross-section and 15 time-series) 20*5*15 = 1500 observations. If I have 14
independent variables (iv), should I assume that I have 1500 - (14 +1) =
1485 df? 
            Thanks in advance
