This document discusses duality in linear programming. It begins by introducing the concept of a dual problem for a given linear program, which seeks to find tighter bounds on the optimal value by minimizing a linear function subject to constraints derived from the original problem. The document then generalizes this process to define the dual problem for any linear program with inequality or equality constraints, whether variables are non-negative or unconstrained. It aims to provide an introduction to duality theory and how dual problems can help analyze optimality in linear programming problems.

First part shows several methods to sample points from arbitrary distributions. Second part shows application to population genetics to infer population size and divergence time using obtained sequence data.
NagoyaStat #9 で使用した資料です(公開に当たって口頭の内容を補完したものになります)。
「StanとRでベイズ統計モデリング」の第7章になります。
内容は単に回帰分析を行うだけではダメなケースについての取り扱い方について、著者の流儀について理解しようというものになります。
