Statistics

 WeightedMovingAverage
 compute weighted moving averages for a data set

 Calling Sequence WeightedMovingAverage(X, Y, options)

Parameters

 X - Y - average options - (optional) equation(s) of the form ignore=value; specify options for the WeightedMovingAverage function

Description

 • The WeightedMovingAverage function computes weighted moving averages for a set of observations. This is a special case of the LinearFilter command.
 • The first parameter X is a single data sample - given as e.g. a Vector. Each value represents an individual observation.
 • The second parameter Y is the average - given as e.g. a Vector. Each value represents a average coefficient.

Options

 The options argument can contain one or more of the options shown below. These options are described in more detail in the Statistics[Mean] help page.
 • ignore=truefalse -- This option is used to specify how to handle non-numeric data. If ignore is set to true all non-numeric items in X will be ignored.
