Timeseries Forecasting
Timeseries forecasting models are characterized by three fields:
- forecast timestamp: the date and time of the predicted event or observation and is passed into the timestamp field. (data type: integer unix timestamp in seconds)
- run_date: the date on which the model was run and the prediction was generated and is optionally passed in as a tag. (recommended data type: str or integer unix timestamp)
- lag: the number of days between the forecast timestamp and run date and is optionally passed in as a tag (recommended data type: int)
You will likely need to extend your model's delayed actuals join window. Reach out to [email protected] for help with this.
For example, if you run a model on Monday to predict the temperature on Friday, the run date would be Monday's date, the forecast timestamp would be a timestamp for a time on Friday and the lag would be four days.
