Here you can find how to get started quickly with scikit-hts. We’ll use some sample (fake) data. More extensive usage, including a solution for Kaggle’s M5 Competition, can be found in the scikit ...
Webb12 feb. 2024 · Thanks very much for this report! I think this can be pretty easily fixed by using _initialization_heuristic if we have at least 10 observations and use _initialization_simple if we have fewer than that.. I could not see a good workaround for this at the moment, other than the fact that if you are focused on linear (not muliplicative) … WebbSimpleExpSmoothing.fit (smoothing_level=None, optimized=True) [source] fit Simple Exponential Smoothing wrapper (…) Parameters: smoothing_level ( float, optional) – The …
