Alongside linear regressions, Tableau has added regularised linear regression and gaussian process regression to the model types you can run in the Model Quantil and Model Percentile functions in the calculation window.
In 2020.3, we introduced the MODEL_QUANTILE and MODEL_PERCENTILE table calculation functions. By default, these functions use linear regression to generate predictions and explore relationships within your data. Now in 2020.4, you’ll be able to leverage two more models: Gaussian process regression and regularized linear regression. With more models supported, you have greater flexibility and can choose the model that best fits your use case.Documentation. https://help.tableau.com/current/pro/desktop/en-us/predictions_choosing_model.htm
