Beginning this issue, we are starting an initiative to engage more student members of the IMS in Bulletin reading and independent research activities. The new Student Puzzle Corner will contain one or two problems in statistics or probability. Sometimes, solving the problems may require a literature search.
Current student members of the IMS are invited to submit solutions electronically (to with subject “Student Puzzle Corner”).
Deadline January 15, 2014.
The names and affiliations of all student members to submit correct solutions, and the answers to the problems, will be published in the next issue of the Bulletin. The Editor’s decision is final.
