I have two continous variables mes1 and mes2. mes1 is a test performed
on a group individuals by one observer and mes2 contains the results of
the same test performed by another observer on the same group of
individuals. I want to estimate the intraclass correlation between the
two observers, but can't find out how. I'm aware that -loneway- can
estimate this if you have a measurement and a grouping variable. Do I
have to transform my data in some way to use -loneway- (how?) or is
there a command which calculate the intraclass correlation straight
away? Some ideas? Thank you in advance.
