lnpr's Issues

A.1.5 の mu_N を求めるコードに関して

上田先生、はじめまして。
大変分かりやすくて楽しい書籍、ありがとうございます。先生の生徒さんがうらやましいです!

gauss_gamma.ipynb に関して質問させて下さい。

mu_N = 1.0/(N+beta_0)*sum(samples) + beta_0/(N+beta_0)*mu_0

書籍の内容からすると

mu_N = 1.0/(N+zeta_0)*sum(samples) + zeta_0/(N+zeta_0)*mu_0

が正しいように見えるのですが、いかがでしょうか?結果がさほど変わらないのであまり自信がなく、ご質問させて頂きました。

オリジナルの結果: mu_N == 207.14285714285714
修正の結果: mu_N == 208.33333333333331
