Making Bayesian Statistics Accessible to Everyone – Edition 3: Understanding the Beta-Binomial Distribution

Introduction This third edition is presented as a focused interlude to formally introduce an essential building block of Bayesian modeling: the Beta-Binomial distribution. This distribution is not only elegant from a mathematical perspective, but also…

Introduction to Statistical Decision Theory- Edition 5: Optimal Decision Rules

Content Main topics: Admissible decision rules Bayes decision rules Minimax decision rules Context: Parameter estimation 1. Admissibility: The Idea In statistical decision theory, we aim to choose good decision rules from all possible ones. Let…

Making Bayesian Statistics Accessible to Everyone – Edition 4: Summarizing and Interpreting Bayesian Results

Introduction In Edition 2, we explored motivating examples that helped solidify key Bayesian ideas, from credible intervals to beta-binomial modeling and clinical trial analysis. Edition 3 examined the mathematical foundations of the Beta-Binomial distribution, a…

Introduction to Statistical Decision Theory- Edition 6: Bayes Decision Rules

1. From Classical to Bayesian Decision Making In earlier editions, we defined: Statistical decision problems Point estimation, hypothesis testing, confidence intervals Loss functions and risk functions Concepts of admissibility, dominance, and optimality In Edition 6,…

Making Bayesian Statistics Accessible to Everyone – Edition 5: A Bayesian Use Case – Monitoring Vaccine Efficacy in a Phase 3 Trial

Summary Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and the resulting disease, COVID-19, have afflicted tens of millions of people globally. The urgent need for safe and effective vaccines led to a large-scale phase 3…

Introduction to Statistical Decision Theory- Edition 7- Application: Bayesian Estimation under Weighted Quadratic Loss

Introduction In the previous edition, we explored how decision theory provides rules for estimating unknown parameters using loss functions and Bayesian rules. Now, we go one step further by introducing weighted quadratic loss and how…
