Welcome to Stata and Statalist!

I don't really understand your question. If you have a number of raters and one subject,  you can estimate the proportion of raters who assign each category to the subject. Call them p1, p2, p3, with p1 + p2 + p3 =1.  How is kappa to be defined?

Hi,

I was previously a user of SAS and have recently switch to stata.

My situation involves multiple raters on a 3 point ordinal scale. I have one subject. I am unsure which or if there is a package that will allow me to do this.

thanks, George
