The Tableau Statistical Service manages the statistical engine behind Explain Data and predictive modelling functions on Tableau Server. This service is available in Tableau Server 2022.1 and later.
The Tableau Statistical Service is automatically installed on any node where VizQL is installed.

Impact if the Tableau Statistical Service fails
If the Tableau Statistical Service stops working, Explain Data will be unavailable, and views that contain calculations with predictive functions MODEL_PERCENTILE and MODEL_QUANTILE won’t render.
If there is increased usage of Explain Data or predictive modelling functions on Tableau Server, you may benefit from installing additional instances of the Tableau Statistical Service on nodes running VizQL. For more information on configuring the topology of a Tableau Server node, see Configure Nodes.
The Statistical Service creates two sets of log files:
control_statsservice*.log: These logs will contain information about the service starting and being enabled.
stdout_statsservice_*.log: These logs will contain information about status and errors.
For more information, see Tableau Server Logs and Log File Locations.
