I have a time series dataset for forecast using Holt-winters model, but my problem is the time series contains breaks or change point, [![enter image description here][1]][1]
Should we remove the first break? Or is there any other solution for managing breaks in the Holt-Winters model?
Knowing that by removing the first breaks data the error rate of my model decrease.
