The reason that -gen peso = sum(pesoan)- gives different results is
that gen refers back to the build in functions from Stata. -egen- is
specifically designed to extend these functions. To find a list of
built in functions type -help function-. You can than find that the sum
function results in a running sum.

Hope this helps,
