Facebook先知中的'yhat'、'yhat_lower'、'yhat_upper'是什么？
What is 'yhat', 'yhat_lower', 'yhat_upper' in Facebook prophet?
我正在用 facebook prophet 解决一个时间序列问题，我无法理解其中的内容
'trend','yhat_lower','yhat_upper','trend_lower','trend_upper','additive_terms','additive_terms_lower','additive_terms_upper','multiplicative_terms','multiplicative_terms_lower','multiplicative_terms_upper'
在预测之后。
谢谢
来自 Quick Start:
The predict method will assign each row in future a predicted value which it names yhat. If you pass in historical dates, it will provide an in-sample fit. The forecast object here is a new dataframe that includes a column yhat with the forecast, as well as columns for components and uncertainty intervals.
因此
yhat：预测yhat_lower、yhat_upper：不确定区间
