It’s been a quiet couple of weeks around here, but this week there was a good bit of action.   I completed 100 new video solutions this week for section D.   That completes all the video solutions for the problems in D.1 and D.2, and I have 9 left to go in section D.3.5 before D.3 will be totally complete.

I hope to finish up the D.3.5 solutions and continue to add a bunch more video solutions next week.  My goal is to get to complete video solutions as soon as possible, and currently I have 116 more to go.

This week, I made a significant correction to a formula in lesson E.2.4.  There was a critical typo in the formula for the autocorrelation function of the ARMA(1,1) models.   This has now been fixed in the lesson, the handouts, the problems, and the E.2 summary sheet.  Please get new copies of these files to replace the ones with the error as soon as possible.

I also created a new lesson to help guide your practice time between finishing the lessons and starting on sample exam.   It is found just below section E of the lessons tab, in a new section called “What to do after you finish the lessons”.  I know, mysterious naming conventions, right?   I hope that you will find this video helpful for you to plan your time once you have finished watching the lessons.  As always, feedback is appreciated.

Finally, I added 10 or so problems in section E this week, to lessons E.1.2, E.2.2, E.2.3, and E.2.4.

As always, if you find that you need a missing video solution, please let me know and I will post it as soon as possible.
