Improve predictive analysis results by configuring prediction settings to use a specific set of closed Cases in the calculation. For example, you can define an interval to ensure that the calculation only uses Cases that completed recently.

The system opens the Predictive Settings dialog box, which provides options to select a time interval and a categorical column:

Limiting predictive data by time interval
Ensure that the prediction calculation provides realistic results by defining the time interval for closed Cases. Predictive analysis works best when you use recent or near real-time data for the prediction model. You might also want to exclude data that contained an irregularity that would skew the results in the prediction model. For example, if an unusual supply chain issue occurred early last month that is now resolved, then you can limit the data to start from a time period after the resolution.
The default time interval for predictive analysis is First Date Recorded to Now. This interval means that the system includes all closed Cases from the first date and time recorded in the dataset to the current date and time. If the View creator used scheduling to keep the data fresh, then these default values might still provide recent data.

If you want to select a categorical column in addition to defining a timestamp interval, in the Column name field, select the column and then click Apply Settings to return to the Predictive Analysis page. You can apply only a timestamp interval, only a categorical column, or both settings.

Applying a Categorical Column use case
In this use case, you want the prediction calculation to match the City column value between closed and open Cases. For example, if the city for open Case 346 is Boston, then you want the system to only use closed Cases from Boston to predict when Case 346 will finish. The same would be true for Cases in Chicago, Atlanta, Austin, and all other cities in the dataset. You want the system to only use closed Cases from each respective city to predict when open Cases from the same city will complete.
Using the following sample dataset, when you do not select a column, the Predictive Analysis page shows None for Selected Column and predicts that Case 346 will finish in 3hs42m:

To apply a categorical column, click the Analyses Options icon and select Prediction Settings to open the Predictive Settings dialog box. In the Categorical Column Selection section, select City and then click Apply Settings, as shown in the following figure:

The system closes the Predictive Settings dialog box and returns to the Predictive Analysis page, which now shows City for Selected Column. To run the calculation with the City column selection, in the upper-right corner, click Perform Prediction. The system now predicts that Case 346 will finish in 46m3s:
