The PredictabilityEstimateVersion API is a scriptable object used in Predictive Intelligence stores.

This API requires the Predictive Intelligence plugin (com.glide.platform_ml) and is provided within the sn_ml namespace.

Use this API when working with predictability estimate versions based on PredictabilityEstimate API objects in the PredictabilityEstimate store.

The system activates the most recent version of the predictability estimate when it completes training, and only allows one version to be active at a time. However, you can activate any previously trained version you want to use to make predictions.

Methods in this API are accessible using the following PredictabiltyEstimate methods:
