Introduction to Time Series Forecasting: Smoothing Methods
WebIn time series forecasting, data smoothing is a statistical technique that involves removing outliers from a time series data set to make a pattern more visible. Inherent in the collection of data taken over time is some form of random variation. Smoothing data removes or reduces random variation and shows underlying trends and cyclic components. WebSmoothing is the process of removing noise from raw a input signal. Several techniques exist, from simple to more complicated. Smoothing methods are implemented by the Smoothing class.
