Hej Statalist,
I have a problem, as I want to aggregate my panel data under certrain conditions. I have trade data that conisits of the variables year, Exporter(partner), Importer(reporter), commoditycodes (#97 different one) and trade Values. Now i want to sum up the Trade Valus for Exporter, Importer and Year if for different groups of the commiditycode. For example i want a groups of commoditycodes: 1-24, 25-40, 40-99).
My data set looks like this:
I tried to use the collapse command, but I can't make it work for the different groups of commoditycodes.
This code is just deleting all the observations if the commoditycode is bigger than 24.
Anyone has an idea how to solve it? Thank you very much in advance!!

Anyone has an idea how to solve it? Thank you very much in advance!!
