Question #645803 on Graphite changed: https://answers.launchpad.net/graphite/+question/645803
Wenna gave more information on the question: - Yes, start time of each series has been changed to one week prior to the start time. And indeed, end time remains the same, so, your series are included in training set. Why shouldn't it? Because we are actually trying to predict the series. In graphite we plotted the HW prediction and data together to compare. The future prediction is not supported as you said, so the prediction result is indeed within the same period of time as series. Again an example, we input data from -24hours till now, and call hw on this series. Then in Graphite it would include data from -24hours-1week till now as training data, and output prediction from -24hours to now. That's not prediction because what we want to predict is the input of the prediction. It makes more sense if training data come from -24hours -1week till -24hours. In this case, even though we know about the data from -24hours till now, we are still forecasting. -- You received this question notification because your team graphite-dev is an answer contact for Graphite. _______________________________________________ Mailing list: https://launchpad.net/~graphite-dev Post to : [email protected] Unsubscribe : https://launchpad.net/~graphite-dev More help : https://help.launchpad.net/ListHelp
