[R] Interrater and intrarater variability (intraclass correlationcoefficients)
It sounds as thought you are interested in Hoyt's Anova which is a form of generalizability theory. This is usually estimated using by getting the variance components from ANOVA.> -----Original Message----- > From: r-help-bounces at stat.math.ethz.ch > [mailto:r-help-bounces at stat.math.ethz.ch] On Behalf Of Karl Knoblick > Sent: Tuesday, May 16, 2006 6:10 AM > To: r-help at stat.math.ethz.ch > Subject: [R] Interrater and intrarater variability > (intraclass correlationcoefficients) > > Hello! > > I want to calculate the intra- and interrater reliability of > my study.

[R] Interrater and intrarater variability (intraclass correlationcoefficients)
Dear Harold, Thanks! I searched for Hoyt's Anova in R - but without success. Do you know if there is something available in R?

[R] Interrater and intrarater variability (intraclass correlationcoefficients)
Well, depending on your design you can get the variance components from lmer or aov. Instead of looking for Hoyt's ANOVA in R, you should look at the method itself and then see how you can use the methods in R for estimating variance components.> -----Original Message----- > From: Karl Knoblick [mailto:karlknoblich at yahoo.de] > Sent: Wednesday, May 17, 2006 1:50 AM > To: Doran, Harold; r-help at stat.math.ethz.ch > Subject: AW: [R] Interrater and intrarater variability > (intraclass correlationcoefficients) > > Dear Harold, > > Thanks!
