Dear Listers,

I am new to Stata and have the following question.

I have education survey data where the data are ordered by school and student and more pertinently the variable “school.” The data are ordered by the variable “school” and would give 0 0 0 0 1 1 1 1 etc. I have created appropriate school-level variables but the problem is that the values of the school-level variables are repeated for the same school, whereas I want only one record per school for some of the school-level variables. I tried various merging file schemes but none work. Any help is highly appreciated

Thanks

Russell
