确认时间列、频率、目标和预测区间,按时间排序并处理缺口。检查平稳性,选择合理参数,使用时间切分验证,输出预测值、区间和误差,并说明外部冲击限制。
Tool routing
- Use
get_schemato identify the time column, target column, table name, and available covariates. - Use
query_dataonly to verify ordering, missing timestamps, frequency, and enough rows for modeling. - Use
run_analysiswithanalysis_name="Time_Series_ARIMA"for the actual forecast computation. - Use
generate_charton the returned forecast or diagnostic result tables afterrun_analysissucceeds.
