Answer 1

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
