Я пытаюсь использовать specials
при прогнозировании с использованием пакета fable, но я не могу понять синтаксис, как их использовать, и я не смог найти пример, который мог бы использовать в качестве руководства .
Ниже приведен простой пример попытки использовать окно с прогнозной моделью MEAN , но оно дает мне ошибку.
Любая помощь очень приветствуется!
