Betreff: st: rowtotal & adding columns
I am trying to create new columns that are the sum of existing columns, but
the resulting numbers are not what is expected. As an example, I manually
entered the following var1 var2 var3(no decimals); then used egen
tot=rowtotal(var*); then used gen add=var1+var2+var3.
The resulting tot and add are okay for smaller numbers, but not for the
larger numbers. The last two rows should be 370,370,367 and 964,964,961
respectively. Am I doing something incorrectly? I can't seem to figure it
out...
Thanks,
Ryan
