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 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
