NEAS Regression Analysis/Time Series Practice Exams?

[al1835]

So, as I go through the Final Exam Practice Problems sections in the Regression Analysis and Time Series forums of NEAS, I am coming across student comments about this question number or that question number from the Practice Exam. However, I do not see a practice exam posted anywhere in either of those forums. Is this something that was posted at some point in the past but then got taken down?

The practice problems are the practice exam...NEAS just posts them in pieces, as opposed to one PDF file. From what I've been led to believe, the actual exam is quite similar to these problems. If it isn't, I'm screwed.

If you are talking about the references to 4.5 Durbin-Watson, 3.10, 3.7 & 3.8, etc. in the Time Series forum, there is a Time Series Practice Exam attached to the thread Condensed pdf (started by jjgoodluck) which uses the numbering system that is being referred to in the forum.

Thanks! That's what I was looking for. I mean, it looks similar/same as the practice problems but using a different numbering system, but I still find it helpful.

Anyone know if those Seasonality formulas will be on the exam? They appear to only be used once in the Seasonality module, then never mentioned again (and there wasn't any Final Exam Practice Problems on them either).

I wonder the same too. They seem to be stressed quite a bit in the introductory notes for module 5 ("Know equation 15.28...", etc.). I'm going to look over them just to be safe.

15.28 is Smoothing (which they've asked quite a bit)...Seasonality is a little different. I'm going to read over it, and look at the homework on it...otherwise, as a wise person taught me for FAP1.....Skip it.

You're right.

The de-seasonalization calculations are pretty straightforward after looking at the module 4 practice problem although the concepts seem to be what the author stresses.
