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? Steve sjsamuels@gmail.com On May 1, 2011, at 7:24 PM, volsmd99 wrote: 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 * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/ * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
