Secondly we predicted the CPI index for January, February, and March 2020 by using the gray prediction model. Thirdly, the trend of the forecast data was visualized with Python. Finally, the predicting result was compared with the real data, and the reason for the difference was analyzed....
For time series forecasting, multivariate grey models are excellent at handling incomplete or vague information. The GM(1, N) model represents this group of models and has been widely used in various fields. However, constructing a meaningful GM(1, N) model is challenging due to its more comp...
Greykite offers components that could be used within other forecasting libraries or even outside the forecasting context. ModelSummary() - R-like summaries of scikit-learn and statsmodels regression models. ChangepointDetector() - changepoint detection based on adaptive lasso, with visualization. ...
