MovingAverage
public class MovingAverage (Code)
	A utility class for calculating moving averages of time series data.

Method Summary
public static TimeSeriesCollection	createMovingAverage(TimeSeriesCollection source, String suffix, int periodCount, int skip) Creates a new TimeSeriesCollection containing a moving average series for each series in the source collection. Parameters: source - the source collection. Parameters: suffix - the suffix added to each source series name to create thecorresponding moving average series name. Parameters: periodCount - the number of periods in the moving average calculation. Parameters: skip - the number of initial periods to skip.
public static TimeSeries	createMovingAverage(TimeSeries source, String name, int periodCount, int skip) Creates a new TimeSeries containing moving average values for the given series.
public static XYDataset	createMovingAverage(XYDataset source, String suffix, long period, long skip) Creates a new XYDataset containing the moving averages of each series in the `source` dataset. Parameters: source - the source dataset. Parameters: suffix - the string to append to source series names to create target series names. Parameters: period - the averaging period. Parameters: skip - the length of the initial skip period.
public static XYDataset	createMovingAverage(XYDataset source, String suffix, double period, double skip) Creates a new XYDataset containing the moving averages of each series in the `source` dataset. Parameters: source - the source dataset. Parameters: suffix - the string to append to source series names to create target series names. Parameters: period - the averaging period. Parameters: skip - the length of the initial skip period.
public static XYSeries	createMovingAverage(XYDataset source, int series, String name, double period, double skip) Creates a new XYSeries containing the moving averages of one series in the `source` dataset. Parameters: source - the source dataset. Parameters: series - the series index (zero based). Parameters: name - the name for the new series. Parameters: period - the averaging period. Parameters: skip - the length of the initial skip period.
public static TimeSeries	createPointMovingAverage(TimeSeries source, String name, int pointCount) Creates a new TimeSeries containing moving average values for the given series, calculated by number of points (irrespective of the 'age' of those points).

Method Detail

createMovingAverage
public static TimeSeriesCollection createMovingAverage(TimeSeriesCollection source, String suffix, int periodCount, int skip)(Code)
	Creates a new TimeSeriesCollection containing a moving average series for each series in the source collection. Parameters: source - the source collection. Parameters: suffix - the suffix added to each source series name to create thecorresponding moving average series name. Parameters: periodCount - the number of periods in the moving average calculation. Parameters: skip - the number of initial periods to skip. A collection of moving average time series.

createMovingAverage
public static TimeSeries createMovingAverage(TimeSeries source, String name, int periodCount, int skip)(Code)
	Creates a new TimeSeries containing moving average values for the given series. If the series is empty (contains zero items), the result is an empty series. Parameters: source - the source series. Parameters: name - the name of the new series. Parameters: periodCount - the number of periods used in the average calculation. Parameters: skip - the number of initial periods to skip. The moving average series.

createMovingAverage
public static XYDataset createMovingAverage(XYDataset source, String suffix, long period, long skip)(Code)
	Creates a new XYDataset containing the moving averages of each series in the `source` dataset. Parameters: source - the source dataset. Parameters: suffix - the string to append to source series names to create target series names. Parameters: period - the averaging period. Parameters: skip - the length of the initial skip period. The dataset.

createMovingAverage
public static XYDataset createMovingAverage(XYDataset source, String suffix, double period, double skip)(Code)
	Creates a new XYDataset containing the moving averages of each series in the `source` dataset. Parameters: source - the source dataset. Parameters: suffix - the string to append to source series names to create target series names. Parameters: period - the averaging period. Parameters: skip - the length of the initial skip period. The dataset.

createMovingAverage
public static XYSeries createMovingAverage(XYDataset source, int series, String name, double period, double skip)(Code)
	Creates a new XYSeries containing the moving averages of one series in the `source` dataset. Parameters: source - the source dataset. Parameters: series - the series index (zero based). Parameters: name - the name for the new series. Parameters: period - the averaging period. Parameters: skip - the length of the initial skip period. The dataset.

createPointMovingAverage
public static TimeSeries createPointMovingAverage(TimeSeries source, String name, int pointCount)(Code)
	Creates a new TimeSeries containing moving average values for the given series, calculated by number of points (irrespective of the 'age' of those points). If the series is empty (contains zero items), the result is an empty series. Developed by Benoit Xhenseval (www.ObjectLab.co.uk). Parameters: source - the source series. Parameters: name - the name of the new series. Parameters: pointCount - the number of POINTS used in the average calculation (not periods!) The moving average series.
