Как вы можете видеть в приведенном выше коде, я получаю сообщение об ошибке Hessian в единственном числе, когда я пытаюсь построить модели из моего безымянного фрейма занятости. Я спрашиваю, что именно относится к сообщению об ошибке? Я попытался использовать меньше ковариат, и ничего не изменилось, и я действительно не знаю, что означает R, когда он говорит, попробуйте предоставить начальные значения.
