Hello Muhammad,
I hope your well.
I used the link <a href="http://www.restore.ac.uk/Longitudinal/labs/lab2.do" target="_blank" class="newlyinsertedlink">http://www.restore.ac.uk/Longitudinal/labs/lab2.do</a>
Which you had sent me and I must say I found it very useful. I was also wondering if you had any resources which tell you how to add a wave dummy variable into my BHPS dataset. I have variables sctype, smoker, ncigs, pid,age, wave and cigarettes and now wanted to a dummy variable to wave to see how it changes over time.
Would you or any statalist users be able to advise how to do this?
Regards
Yasir
