New Projective Maximum Entropy Framework Unifies Statistical Reference Distributions

Researchers have introduced Projective Maximum Entropy, a novel framework for constructing reference distributions in statistics. This approach addresses limitations with unnormalized statistical models and prescribed admissible regions. The framework establishes a universality theorem, unifying various entropy and score constructions, and characterizes the common optimizer as a q-exponential density. Additionally, it provides a method to uniquely determine the deformation parameter of a bounded-support reference distribution based on a specified Mahalanobis acceptance region. AI
