Hi Caliph Try collapse (sum) duration cost, by(id gender age) for a data that look like this one +---------------------------------------+ | id duration cost gender age | |---------------------------------------| 1. | 1 8 50 MALE ADULT | 2. | 1 10 40 MALE ADULT | 3. | 1 3 30 MALE ADULT | 4. | 2 7 20 FEMALE YOUNG | 5. | 2 9 60 FEMALE YOUNG | |---------------------------------------| 6. | 2 6 100 FEMALE YOUNG | 7. | 2 8 20 FEMALE YOUNG | +---------------------------------------+ Aminu ________________________________ From: Caliph Omar Moumin <sheikmoumin@yahoo.com> To: "statalist@hsphsun2.harvard.edu" <statalist@hsphsun2.harvard.edu> Sent: Sunday, August 12, 2012 7:17:25 PM Subject: Re: st: How to reshape or collapse multiple observation per id as one observation per id Dear Aminu How do i keep other variables like gender, agegroup, and other string variables?

I have a dataset which is in long format with multiple observation per id, and no time period. The dataset is also unbalanced id duration cost gender agegroup plus other string variables (up to 5 variables) I want to create a dataset with one observation per id by adding each ones multiple observation in both variables duration and cost id duration cost (other variables) 1 8 50 string(or constant) 1 10 40 >>>>>>>>>>>>> 1 3 30 >>>>>>>>>>>>> 2 7 20 >>>>>>>>>>>>> 2 9 60 >>>>>>>>>>>>> 2 6 100 >>>>>>>>>>>>>> 2 8 20 and so on up to 20,000 observation which i have one up to 10 observation per id. I wanted to reshape my dataset as Id duration cost (other variables) 1 21 120 unchanged 2 30 200 >>>>>>>>> I tried the reshape command. And it is creating many variables of duration and cost instead of adding as one variable id duration1 duration2 duration3 duration4........... 1 8 10 3 . I tried the collapse command and it is giving me only the mean value. But i wanted the total value. I would appreciate you if you could help?
