Hi I am trying to better understating the similarities and differences between trending and forecasting options in tableau. I added both on a random data set - see picture. Blue is trend, red is forecast a year out.
Can someone help me understand how they work?
You can get all the math behind the trend and forecast models. Did you try the describe options?
Ref line is linear regression, forecast is exponential smoothing. If you have time series, best use forecast.
