У меня есть некоторый код Stata, и я хочу повторить результаты в R .Однако даже с одним и тем же набором данных и, как мне кажется, одним и тем же кодом, я получаю в R результаты, отличные от результатов в Stata.Я думаю, это может быть потому, что Stata делает порядок регрессии отличным от введенного.
Нужен ли мне точно такой же порядок, как в Stata, чтобы получить те же результаты, и как я могу это сделать?
Я изменил все переменные на факторы и попробовал еще раз, но проблема все еще существует.
Я заметил, что когда я изменяю порядок объясняющих переменных, я получаю разные результаты, но я не нахожу "правильный порядок" для репликации результатов Stata.
