Hi All., Following on from all the help I received earlier ..
Just so as you know a well known text book (T&F) uses "repeated observations" - I think perhaps they meant repeated measures in retrospect I am a total beginer to ARIMA, but have read a a basic text. I read that ARIMA requires a minimum of 50 repeated measures in time (repeated measures)- Unfortunately, I have 8 repeated measures of the same psychiatirc appraisal the sample sizes was decent (n > 200). Is ARIMA violated or does it remain robust under such circumstances? Is there a viable alterative to ARIMA out there to analyze a trend of 8 repeated measures w. > 200 cases? Many thanks Stephen ???? ?"? ???? ???? http://mail.nana.co.il [[alternative HTML version deleted]] ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
