# Tableau Statistical Service

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 through to 2023.1.x.

**Note:** The Statistical Service was retired in version 2023.3.0 and no longer shows up on the status page or in the output of the tsm status command.

## Server configuration

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.

## Performance

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](https://help.tableau.com/v0.0/server/en-gb/config_nodes.htm).

## Log files

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](https://help.tableau.com/v0.0/server/en-gb/logs_loc.htm).
