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.

Exponential Smoothing: Formula, Method, and Solved Examples

WebbDouble Exponential Smoothing is better at handling trends. Triple Exponential Smoothing is better at handling parabola trends. An exponenentially weighted moving average with a smoothing constant a, corresponds roughly to a simple moving average of length (i.e., period) n, where a and n are related by: a = 2/(n+1) OR n = (2 - a)/a. WebbAmong the time series models, I have tried (S)ARIMA, exponential methods, the Prophet model, and a simple LSTM. 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.
