WebbIndependent multi-series forecasting¶. In univariate time series forecasting, a single time series is modeled as a linear or nonlinear combination of its lags, where past values of the series are used to forecast its future.In multi-series forecasting, two or more time series are modeled together using a single model. In independent multi-series forecasting a … Webb11 apr. 2024 · Feb 6, 2024 at 11:22. Add a comment. 2. To apply the log transform you would use numpy. Numpy as a dependency of scikit-learn and pandas so it will already be installed. import numpy as np X_train = np.log (X_train) X_test = np.log (X_test) You may also be interested in applying that transformation earlier in your pipeline before splitting …
