no teaching Thursday March 17 !

I'm sorry to report, and rather late, the evening before, that I've fallen ill -- and let me be brave enough and specific enough to tell you I've had a positive covid test. I'm just moderately ill, no bothersome symptoms, and it feels like having a somewhat unusual winter cold. Though I'm up and about, and able to work, I do follow the UiO and Math Dept rules, and stay at home, in splendid isolation, for a few days.

Within a few days I'll upload an extended Nils Collection of Exercises and Lecture Notes, with emphasis on (a) estimation in AR(p), MA(q), ARMA(p,q); (b) gentle start on Ch 4, frequency domain modelling, analysis, applications. So please start reading the first two sections there. Ch 4 is our last "major weightlifting" for the course. 

We will also soon start doing *earlier exam set questions*, which you find at the course website; these are from 2010, 2012, 2016, 2018, apparently. 

More information soon.
