st: counting and eliminating data
Can someone please set me in the right direction for coding a program to
count and eliminate data if it doesn't meet a certain criteria?
I have survey data taken over 26 years and the survey area is divided
into subareas. I want to only include a subarea if data was collected 13
years out of the 26 and data must have been collected 2 years of the first
5 years and 2 years of the last 5 years. If the subarea does not meet that
criteria, I want Stata to drop that subarea from the analysis. At the
moment, I'm having to look at everything individually and it takes several
days to eliminate subareas.
