Ok, thanks for your reply firstly.
I'm using EViews6. I wanna make Unit root test, cointegration test, Husman test, and OLS test. But only the Unit root test could be processed and I have been told that too much data to process while I was tring to run others....How can I do?

I'm facing a big problem and I'm really confused by this:
I put around 151,000 data and system told me that the test could not be operated because there are so many data, is this really?? If yes, so how many data it could be??

Thanks!
