  • de Chaisemartin and D'Haultfoeuilleではstataのdid_multiplegtfirstdiff_placeboweightのoptionコマンドがない。また、Cicalaのreplicationでcluster=pca_modateを指定するとエラーが出る。
  • Borusyak et al.で被説明変数に"y"という引数を入れるとエラーが出る。
  • CicalaのreplicationでGardnerのdid2sbootstrap=Trueを指定しないとエラーが出る。

@ume-hayato 確認してほしい.

Gardnerのdid2sはLarge Matrixに対してAnalytical Standard Errorを計算できない. これはパッケージの使用っぽい.
kylebutts/did2s#12

ただし, bootstrap=Trueにしても別のエラーが出る. 原因は不明だがStataの用にImputation自体を実装して対応.

de Chaisemartin and D'Haultfoeuille のRパッケージはここ3年メンテナンスされてなく, Stataのパッケージに追いつけていない模様.
kylebutts/did2s#19

なので, #3 のように問題を解決できない.
