Simultaneous estimation of multiple discrete unimodal distributions under stochastic order constraints

ArXi:2603.11532v1 Announce Type: cross We study the problem of estimating multiple discrete unimodal distributions, motivated by search behavior analysis on a real-world platform. To incorporate prior knowledge of precedence relations among distributions, we impose stochastic order constraints and formulate the estimation task as a mixed-integer convex quadratic optimization problem.
