Ben might want to start with:
- search imputation -
from within Stata (not STATA).
Kind regards,
Carlo

Oggetto: st: Missing data question.
Dear all,
I am just starting to learn STATA. I am struggling with missing datas in my
dataset.(82 stocks, historical monthly stock price data for
20years)
I need to take the average of the stock's return for as many year as I can,
where there are so many missing data as the industry is quite volatile
sector.
I decided to use 10years out of 20 years, as I deem appropriate, however
there are still so many missing data and I dont want to simply exlcude them.
I heard that there are some techinic called "imputation".
Could you let me know how to employ this function in STATA?
Many thanks.
Ben
