Jayaram Sethuraman

Overview

Jayaram Sethuraman is a statistician (Florida State University, Emeritus), known for foundational work in probability and Bayesian nonparametrics — most famously the stick-breaking constructive definition of the Dirichlet process — as well as contributions to large-deviations theory and reliability.

Key Contributions / Features

• Stick-breaking construction (Sethuraman 1994): the explicit $P=\sum_n p_n\delta_{Y_n}$ representation of the Dirichlet process with $\text{Beta}(1,M)$ stick-breaking weights — the computational foundation of modern Bayesian nonparametrics.
