HoltLinearModelBuilder

public HoltLinearModelBuilder()

Method Detail

alpha

public HoltLinearModel.HoltLinearModelBuilder alpha(double alpha)

Alpha controls the smoothing of the data. Alpha = 1 retains no memory of past values (e.g. a random walk), while alpha = 0 retains infinite memory of past values (e.g. the series mean). Useful values are somewhere in between. Defaults to 0.5.

Parameters:

alpha - A double between 0-1 inclusive, controls data smoothing

Returns:

The builder to continue chaining

beta

public HoltLinearModel.HoltLinearModelBuilder beta(double beta)

Equivalent to alpha, but controls the smoothing of the trend instead of the data

Parameters:

beta - a double between 0-1 inclusive, controls trend smoothing

Returns:

The builder to continue chaining

toXContent

public XContentBuilder toXContent(XContentBuilder builder,
                                  ToXContent.Params params)
                           throws java.io.IOException

Specified by:

toXContent in interface ToXContent

Throws:

java.io.IOException

build

public MovAvgModel build()

Specified by:
