Hi Everyone,

I had some difficulty finding good data sources, so I am posting the ones I have found.  I hope this helps.  I also found a free Excel Add-in for calculating ARIMA and Autocorrelation in the last site below.

Thanks,

Is there an excel function to determine the sample autocorrelations?

[We have posted an Excel template with the approprate functions in the discussion thread for the Time Series student project.]

Here's another site with a wealth of information:
