スタック形式に変換するところはクリアした。「次はバートレットの検定をやるべし」と親切に書いてあったので、そういうものもあったなあとうっかりやったら、有意差が出た。・・・。ここはひとつ、見なかったことにして、分散分析に進もうか。うむうむ、これが大人の対応ぢゃ。pic.twitter.com/54UH0NZzrU
大学院生指導後(今日が学会の抄録締切って、おい)、ついに R で分散分析に到達。なんだこのラクちんなの。ついでに多重比較は Bonferroni 法。なんと簡単な。なんという堕落、昔は電卓で自乗和を計算したのに。もっと昔の人(私の師匠クラス)はそろばんと暗算?pic.twitter.com/dAWfEODjqo
