Dear All, I am trying to get ICC (Intra class correlation coefficient) for a questionnaire. The questionnaire has about 25 questions and was administered to 50 subjects on two occasions. I want to calculate the reproducibility of the questionnaire administered to the same group of subjects on two occasions. I need to calculate reproducibility of each question administered and not a summary/total score. Each question is not always measured on a same scale.
I read the psy and psychometric packages, however, I do not understand as to how should I organize my data. Each subject has two scores for each question. Is there any other package I can use for this? I am a R novice, so sorry for very obvious questions... Please help. Sincerely, Dr. Smita Pakhale_________________________________________________________________________________ > > [[elided Yahoo spam]] > > ______________________________________________ > R-help@r-project.org mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide > http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, > reproducible code. > ____________________________________________________________________________________ [[elided Yahoo spam]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
