Exponentially Weighted Average----- binmat - binomial boost matrices for exponential smoothers ema - exponential moving average - exact version emaerr - calculate MAE ... An exponential moving average (EMA), also known as an exponentially weighted moving average (EWMA), is a first-order infinite impulse response filter that applies weighting factors which decrease exponentially. The weighting for each older datum decreases exponentially, never reaching zero. This … See more In statistics, a moving average (rolling average or running average) is a calculation to analyze data points by creating a series of averages of different selections of the full data set. It is also called a moving … See more In a cumulative average (CA), the data arrive in an ordered datum stream, and the user would like to get the average of all of the data up until the current datum. For example, an investor may want the average price of all of the stock transactions for a … See more From a statistical point of view, the moving average, when used to estimate the underlying trend in a time series, is susceptible to rare events such as rapid shocks or other anomalies. A more robust estimate of the trend is the simple moving median over n time … See more • Tuned, Using Moving Average Crossovers Programmatically See more In financial applications a simple moving average (SMA) is the unweighted mean of the previous $${\displaystyle k}$$ data-points.
