Retrieve Feature Fit metadata for each backtest. Response contains status and available sources for each backtest of the model.
One of the provided backtestIndex indexes used for submitting the compute request and retrieving Feature Fit.
Start/stop models contain a single backtestIndex response value of startstop.
Other models contain backtestIndex of 0, 1, ..., holdout.
One of the provided source parameters used for retrieving Feature Fit.
Each backtest source can be, at a minimum, training or validation. If holdout is configured for the project, backtestIndex also includes holdout with sources training and holdout.
Source value of training is always available. (versions prior to v2.17 support validation only)
When a start/stop model is trained into validation or holdout without stacked predictions (i.e., no out-of-sample predictions in validation or holdout), validation and holdout sources are not available.
Source holdout is not available when there is no holdout configured for the project.
