Sorry my fault. Of course one has to reset the local sum back to 0 once it has reached the 0.95 for the specific row we are looking at currently. Am 13.07.2011 21:22, schrieb Daifeng He:

Thanks, Scott. The code works and it's exactly what I had wanted. Oliver, your codes look reasonable to me too but when I run them, only the first obs is filled in with values for the two newly-generated variables. I will try to figure it out. Joerg, yes, my weight variables are sorted for each obs, but your codes are illuminating and I learned from them too. Guys, thanks for all your help!
