holtWintersConfidenceArea not doing "predicted forecast deviations". #2768

Closed guismai closed 1 year ago

guismai commented 2 years ago

Here is the definition of this function : holtWintersConfidenceArea(seriesList, delta=3, bootstrapInterval='7d', seasonality='1d') Performs a Holt-Winters forecast using the series as input data and plots the area between the upper and lower bands of the predicted forecast deviations.

We try to get predicted forecast deviations with Graphite in a Grafana Dashboard with a time range from:"now-30d" and to:"now+30d", but nothing in future.

HoltWinters*, linearRegression, etc... nothing in future.

What missing ?

TBH I have no idea why all these forecast function exists, because Whisper do not support future datapoints, so, I suspecting Graphite also has problems with future data too. So, you can do predictions but only up to now, which IMO has quite limited use-case
