Exponential smoothing in the analytical module

[Syndicate_Admin]

Hello, a query is not clear to me if the exponential smoothing in the power bi analytical module is the simple exponential smoothing or the triple holt Winters that you use to make the calculations of the predictions.

In my case the seasonal factor is very important, so holt Winters would adapt much better to my data. On the other hand, simple smoothing is not so much. But it's not clear to me which of the two you use in that analytics module.

I appreciate your answers in advance!

Hi , @Syndicate_Admin 

According to your description, you want to kown about the "exponential smoothing" in Power BI.

For Power View in Excel, we provided two versions of exponential smoothing, one for seasonal data (ETS AAA), and one for non-seasonal data (ETS AAN). Power View uses the appropriate model automatically when you start a forecast for your line chart, based on an analysis of the historical data.

For more information, you can refer to , i hope it will be helpful:

Thank you for your time and sharing, and thank you for your support and understanding of PowerBI! 

Best Regards,
