```Thanks Scott.

If I now want to regress from my 18 years dataset, and
I want the correct number of observations for the
years of interest and the coefficients etc. of the
years of interest in the output, can anyone confirm if
the following is correct

. regress y x1 x2 x3 year11 year12 year13 year15 if
year > 10 & year < 16

Its the last part of the command I was uncertain
If you need further clarification, please let me
know.
