Re: st: weighted kappa more than two raters

["Thoret, Sophie" <SThoret@chu-grenoble.fr>]

Ok so ill try to re-explain better :

I want to calculate a weighted kappa with 4 raters (this is a 10 outcome
answer, that why i want to use a weighted kappa)

So I used the fonction :
            kap var1 var2 var3 var4  , wgt(w)


With the weight prerecorded : w
So i think i don’t have to use first -kapwgt-  ?

If i did :  kap var1 var2, wgt(w)
it’s work for 2 variables, but if i put more than 2 variables it does’t
work, do you know how can i do to calculate a kappa with 4 variables and
using a weigh ?

Thanks again ,
