Michal Shauly-Aharonov, Moshe Pollak, Ygal Plakht
Clinical guidelines recommend maintaining serum potassium levels between 4.0 and 5.0 mEq/L in patients with acute myocardial infarction (MI). These guidelines are based on recent s…
Extreme(ly) mean(ingful): Sequential formation of a quality group
Abba M. Krieger, Moshe Pollak, Ester Samuel-Cahn
The present paper studies the limiting behavior of the average score of a sequentially selected group of items or individuals, the underlying distribution of which, , belongs to…
On the Expectation of the First Exit Time of a Nonnegative Markov Process Started at a Quasistationary Distribution
Moshe Pollak, Alexander Tartakovsky
Let {M_n}_{n\ge 0}$ be a nonnegative Markov process with stationary transition probabilities. The quasistationary distributions referred to in this note are of the form Q_A(x) = li…
Third-order Asymptotic Optimality of the Generalized Shiryaev-Roberts Changepoint Detection Procedures
Alexander G. Tartakovsky, Moshe Pollak, Aleksey S. Polunchenko
Several variations of the Shiryaev-Roberts detection procedure in the context of the simple changepoint problem are considered: starting the procedure at (the original Shir…
On Optimality Properties of the Shiryaev-Roberts Procedure
Moshe Pollak, Alexander G. Tartakovsky
We consider the simple changepoint problem setting, where observations are independent, iid pre-change and iid post-change, with known pre- and post-change distributions. The Shiry…
Select sets: Rank and file
Abba M. Krieger, Moshe Pollak, Ester Samuel-Cahn
In many situations, the decision maker observes items in sequence and needs to determine whether or not to retain a particular item immediately after it is observed. Any decision r…
