Student Puzzle Corner
Anirban DasGupta sets two puzzles, one on probability and one on statistics, about Erdős–Rényi graphs, among the most basic models of random graphs. Random graphs are used to model network data. Take a vertex set equal to $\{1, 2, \cdots , n\}$ where $n \geq 2$. Given two distinct vertices…
We have two problems again—but this time the statistics problem and the probability problem are both based on the same story, and both are somewhat non-standard versions of the birthday problem. Student members of IMS are invited to send us your answers for either or both. The deadline is EXTENDED …
Student Puzzle Editor Anirban DasGupta poses another two problems, and says, “Our statistics problem this time is on universally consistent estimation of the regression coefficients for not necessarily Gaussian errors, and the probability problem is on probabilistic graph theory. The statistics problem is a practically important problem that will make …

Student Puzzle Editor Anirban DasGupta poses another two problems, and says, “Once again, we propose one problem on statistics and one on probability. I think you will find both problems to be new to you and interesting. If you are not able to answer either problem…
Student Puzzle Editor Anirban DasGupta poses another two problems, and says, “For the first time in our problem corner, we will consider a problem that is hard to solve analytically, and we will ask you to write an algorithm to solve the problem as accurately as you can by simulation. …
