st: Merge question.
I am trying to merge 2 datasets.
But everytime, I get different results
(_m==3 has 83 observations in the
first time, 97 in the second, 100 in the
third and 96 in the fourth, and so on).
I tried to set seed and made my sort, stable.
With no success. I also tried to recast double
my merging identifier. No success. I tried to
tostring it. No success either.
Any hints why I obtain these various results?
I verified in both Stata and Excel.
I do not understand why Stata marked 3 to some
observations that belonged to both datasets in the
first trial and not in the second time.
PS: When I work interractivelly, I do not have that problem.
I have 96 observations that matched. So what I am doing
wrong in my stata do file?
