st: question: how do i... |

dear all,

i have the following problem:

i want to construct a variable called margin of victory:

my data set looks something like this:

state votesA votesB votesC votesD

1 10 1 6 21

2 11 2 7 22

3 12 3 8 13

4 1 4 2 3

5 2 5 3 7

my question is:

how do i create a variable called margin_of_victory = votes for 1st place - votes for 2nd place?, i.e. 21-10 for state 1, 22 - 11 for state 2, 13 - 12 for state 3, 4 - 3 for state 4, etc.

i can't do this by hand, since i have a huge data set.

i know that the command

. egen margin_of_victory = rmax (votesforA votesforB votesforC votesforD)

will help me pick the biggest number in each row, but how do i get to choose the 2nd biggest number?

thanks many, and sorry if this is a silly question.

thanks many.

ISB
