Constructor Detail

StudyLowess

public StudyLowess()

Method Detail

getResiduals

public double[][] getResiduals()

Gets the multi-dimensional array of residuals.

Remarks:

In statistical terms a residual is an observable estimate of the unobservable error.

getTension

public double getTension()

Gets the Tension. For more detail see setTension(double).

getWeights

public double[][] getWeights()

Gets the multi-dimensional array of weights.

Remarks:

This is a read-only property.

setTension

public void setTension(double value)

Sets the tension value of the study.

Remarks:

This value must be between 0.0 and 1.0
