        # Stats and Anomaly generated at specific timestamp for specific Feature.
        # The start_time and end_time are used to define the time range of the dataset
        # that current stats belongs to, e.g. prediction traffic is bucketed into
        # prediction datasets by time window. If the Dataset is not defined by time
        # window, start_time = end_time. Timestamp of the stats and anomalies always
        # refers to end_time. Raw stats and anomalies are stored in stats_uri or
        # anomaly_uri in the tensorflow defined protos. Field data_stats contains
        # almost identical information with the raw stats in Vertex AI
        # defined proto, for UI to display.

        #   @return [::Float]
        #     Deviation from the current stats to baseline stats.
        #       1. For categorical feature, the distribution distance is calculated by
        #          L-inifinity norm.
        #       2. For numerical feature, the distribution distance is calculated by
        #          Jensen–Shannon divergence.
        # @!attribute [rw] anomaly_detection_threshold
        #   @return [::Float]

        #     Snapshot Monitoring), start_time is only used to indicate the monitoring

        #     For objectives where time window doesn't make sense (e.g. Featurestore
        #     Snapshot Monitoring), end_time indicates the timestamp of the data used to
        #     generate stats (e.g. timestamp we take snapshots for feature values).
