Hi I am getting a problem where I am merging two datasets together and
the N in the resulting dataset can change if I rerun the program 2 or
more times. I am merging by company code (COCODE) and year which do
not uniquely identify observations in the using dataset, but it seems
to me that that should not matter. I get the same result if I use the
joinby command - the resulting N in the dataset changes if I rerun the
program. I am trying to understand why this might happen and am
stumped at the moment. Does anyone have any suggestions?
