Next low level question.
I often use some of the ICCs (the reference I found most helpful to
these was McGraw, K. O.,S. P. Wong (1996). ?Forming inferences
about some intraclass correlation coefficients.? Psychological
methods 1(1), 30-46.)
I have been replicating some rather suspect work others did on
some other data and Splus was brilliant for replicating what they'd
done in terms of missing data substitution but I found myself rather
laboriously exporting data back to SPSS and running reliability to
get the ICCs I'm familiar with from that. I'm sure I should be able to
take the McGraw and Wong formulae and cook up some functions
to generate the various ICCs in splus but it'll stretch my limited brain
and waste hours. Has anyone already done it and would be willing
to share?
TIA again,
Chris
