StanとRでベイズ統計モデリング(アヒル本)をPythonにしてみる - 目次

Last updated at Posted at 2018-08-16

すでにいくつか記事はありますが、StanとRでベイズ統計モデリングをPythonにしてみました。手元では全て変換し終わっているので、見直してから順次上げていきます。最後のほうの章でstatsmodelsのlowessが2次元に対応していないっぽいのでrpy2からRカーネルにアクセスするという方法でかろうじてFull Pythonを保って(?)います。

実行環境

Jupyter on Docker

実行時にworkspaceにホスト側のファイルをマウントしています。
データは'data'、Stanのコードは'stan'に置いていますので、試してみる場合は筆者のGithubページからダウンロードしてきて適当に置いてください。
書籍の実行結果とは異なる部分もありますが、RStanとPyStanの実装の違いかと思います。(こちらの手違いでしたら教えてください)
