Concordance correlation coefficient

Hi

I have a data set that I have been told I need to perform a concordance correlation coefficient test on. It is a correlation between two measures in a time serie. I have tried to find a totutial here on how to perform this test in SAS but have not been able to find one. I do therefore hope that there is someone on this cummuniti that can help me with this problem.

I have performed a test here https://services.niwa.co.nz/services/statistical/concordance but since this is a web based test where I have no idea of what is going on behind the screen, I would prefere to perform a proper test in SAS.

Kind regards,

Per Nielsen

Re: Concordance correlation coefficient

I'm not sure Cohens Kappa is the correct test for a time series, my stats is getting rusty. 

First determine the appropriate tests that need to occur and then figure out how to perform the test in SAS.

Worked perfectly, got the same results as from the home page, just feels a lot better to have a SAS program doing the analysis. Thanks for this suggestion!

Look at PROC TIMESERIES and the OUTCORR option that looks at auto correlation and partial correlations. 

PROC ARIMA / AUTOREG should also be helpful.

Thanks Reeza for your suggestions. I have had this through a statistician, since I am also a bit rusty on that point, and they suggested this analysis
