None of these is very elegant.
gen pred = 1
replace pred = 2 if p2 == max(p1,p2,p3)
replace pred = 3 if p3 == max(p1,p2,p3)
gen pred = .
forval i = 1/3 {
replace pred = `i' if p`i' == max(p1,p2,p3)
}
gen id = _n
reshape long p, i(id)
bysort id (p) : gen pred = _j[_N]
reshape wide
Are you worried about ties?
