Re: st: if expression involving a variable in a while loop

[Oliver Jones <ojones@wiwi.uni-bielefeld.de>]

Since you want to look at every row/observation separately you might have to use
a for loop? Maybe something like

gen sum = 0
gen n_95 = .

count
local maxrow = `r(N)'
for row = 1/`maxrow' {
   local i=1
   while sum <= 0.95 {
      replace sum = sum + var`i' in `row'
      local sum = sum[`row']
      local `i' = `i' + 1
      replace n_95 = `i' in `row'
   }
}


Best
Oliver
