Should I be trying to replicate the NEAS results?

[NEAS: This is an independent student project. The NEAS postings are suggestions to get you started. You can construct an ARIMA model, compare two or more models for a given era, compare two or three eras by type of model of by model parameters, examine seasonality, test out-of-sample forecasts, and many other items.]

Is anyone else having trouble matching the third regression output example in the excel file? I am having no problem matching the other three but for some reason the third one is giving me trouble.

Also, in regards to n2thornl's post, I was under the impression that we could use the same data that NEAS used in their example. I gather this from the text in the "Time Series: Independent Student Projects" posting that reads:

"We provide the time series on the web site along with specific project templates. If you are not sure that you fully understand the concepts, use these interest rates, for two reasons:

You can compare your results with the examples in the project templates.

You can discuss the modeling of these time series on the discussion forum."

Is there another posting that says something that contradicts this?

[NEAS: Correct. Using the same data and the same eras helps you get started. You still complete the project yourself, but you have an outline.]
