Updates progress report

Tue, 24 Mar 2020

Since the previous report, the Summary sheets for the updated D.1, D.2, and D.3 have been completed, and are available in the Before You Begin section of the course. Today I finished reconstituting the problems sets for the new lesson based on the old lesson problem sets, with many small updates to the problem typed … Continue reading →

D.3 Lesson updates are complete

Fri, 06 Mar 2020

I’ve just uploaded the last new video for lesson D.3.4, and with that, the updated D.3 lessons are complete. D.3 has undergone the most significant changes of the D.1-D.3 set. First, the old D.3.4 lesson on estimating GLM models moved (with a major overhaul as well) to the new D.2.3 lesson. Second, I elected to … Continue reading →
