Simple exponential smoothing prediction model
WebbExponential smoothing is useful when one needs to model a value by simply taking into account past observations. It is called "exponential" because the weight of past observations decreases exponentially. This method it is not very satisfactory in terms of prediction, as the predictions are constant after n+1. Double exponential smoothing WebbThe adaptive-response-rate single exponential smoothing algorithm may have an advantage over single exponential smoothing in that it allows the value of alpha to be modified. For single exponential smoothing, let St be the smoothed value for the t-th time period. Mathematically: S1 = x0. St = αxt−1 + (1−a)St−1.

The SimpleExpSmoothing class from the statsmodels library is used to fit the model. The fit method is used to fit the model to the data, with a smoothing level of 0.5. The model is then used to make 48-step ahead forecasts for the time series data in test.

I have also tried regression models using a number of industrial and financial indices and the product price. Unfortunately, no method has led to an acceptable result. With regression models, the test R^2 is always negative. My ...
