Hi All! I have been trying to define a singe data variable from the given two date variables named YEAR and DATE-MONTH for data from from Jan 01, 2005 to Dec 31, 2010. Also the month variable has breaks for holidays. I need to merge the two variable so I could define the yearly specific date with month to compare trends of stocks across the years. The data looks like . li year day-month in 1/20 +-----------------+ year day-month ----------------- 1. 2010 31-Dec 2. 2010 30-Dec 3. 2010 29-Dec 4. 2010 28-Dec 5. 2010 27-Dec ----------------- 6. 2010 24-Dec 7. 2010 23-Dec 8. 2010 22-Dec 9. 2010 21-Dec 10. 2010 20-Dec ----------------- 11. 2010 15-Dec 12. 2010 14-Dec 13. 2010 13-Dec 14. 2010 10-Dec 15. 2010 09-Dec ----------------- 16. 2010 08-Dec 17. 2010 07-Dec 18. 2010 06-Dec 19. 2010 03-Dec 20. 2010 02-Dec +-----------------+ -- --- Best, --------------- Anees * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
