We prove that the almost-entropic region of order four is not semialgebraic, we get as a corollary Matus’ Theorem, which asserts that the almost-entropic regions of order larger than four are not polyhedral. We discuss the algorithmic consequences of our result.

The authors analyzed self-reported SAT scores and actual SAT scores for five different samples of college students (N=650). Students overestimated their actual SAT scores by an average of 25 points (SD=81, d=0.31), with 10% under-reporting, 51% reporting accurately, and 39% over-reporting, indicating a systematic bias towards overreporting. The amount of over-reporting was greater for lower-sco...

In Homework 1, we did a problem where we calculated the parameters of the Framingham risk score for predicting cardiovascular disease (CVD). In this problem, we will revisit the parameters of the Framingham risk score in a more realistic setting using the more sophisticated optimization tool of linear least squares. In the problem in Homework 1, we determined four parameters of Framingham risk ...
