我正在尝试预测原油价格，并且将日期作为观察指标而不是DateTime
model=SARIMAX(df_crudeoil,order=(3,1,3))
cruderesult= model.fit()
print(result.summary())
crude_forecast=cruderesult.get_forecast(steps=30)
mean_crude=crude_forecast.predicted_mean
print(mean_crude)
结果
9229 54.452931
9230 54.476802
9231 54.503399
9232 54.502871
9233 54.463245
9234 54.477102
9235 54.499619
9236 54.498198
9237 54.470114
9238 54.478136
9239 54.496355
9240 54.494998
9241 54.474783
9242 54.479367
9243 54.493714
9244 54.492724
在查看或将索引转换为日期时间而不是观察号时，我需要帮助，因此它应该看起来像
2020-01-02 54.452931
2020-01-03 54.476802
2020-01-04 54.503399
