Moving Average Calculator (Simple, Weighted And Exponential)
Moving Average Calculator (Simple, Weighted And Exponential): a planned Super Calculator tool. Stub page while the tool and its worked example are prepared.
Moving Average Calculator (Simple, Weighted And Exponential) is a planned calculator in the mathematics section of Super Calculator, covering descriptive and summary statistics.
What this calculator will compute
Inputs: time series data, window length k, method, smoothing factor alpha and centered or trailing.
Outputs: smoothed series, latest smoothed value, series chart points and residuals.
Formula, recorded as scope and not yet verified against a primary source: Simple moving average is the mean of the trailing k observations. Weighted moving average applies linearly increasing weights. Exponential smoothing uses S_t = alpha*x_t + (1-alpha)*S_(t-1), with alpha commonly set as 2/(k+1) to match a k-period simple average.
