Step 2: Create a forecast model

To create your forecast model:

1. Select New forecast model on the Forecast models page. 
2. Enter a name for your forecast model.
3. Select a Data collection. If you do not have one ready, create one.
   The data collection trains the algorithms so they make predictions based on the patterns in the historical data. 
4. Select the algorithm based on your data set in the data collection or keep the default selection.
   The default, Anaplan AutoML, chooses the best algorithm for your data set. PlanIQ works out the maximum length and number of intervals that you can select for your forecast horizon. This is based on the information in the data collection. 
5. Select the time interval and how many intervals you want to see in your forecast. 
6. Optional: Select a country from the Country-specific holiday calendar dropdown.
   This is a good option if you want to take into account a country's public holidays. Whichever country you select, their public holidays are included as an additional related data set in your forecast.
   Tip: Calendars are useful for forecast models that are based on data from a single region. To use this option, ensure that the algorithm supports related data sets.
7. Select your quality metric from the dropdown under Additional settings. See Set accuracy metrics.
8. Select Create forecast model.
   We recommend you check back later and give some time for the model to build. When the model is created, a notification displays in the top-right.
   The right pane displays an overview of the model properties and metrics.
