Constructor Details

ParetoFitting

public ParetoFitting(double[] data,
 double sign)

Constructor. Note that that MUST BE ordered in ascending order by the caller!

Parameters:

data -

sign -

Method Details

getEstimatedParameters

public double[] getEstimatedParameters()

Specified by:

getEstimatedParameters in interface FittingAlgorithm

isFitted

public boolean isFitted()

Method for applying the Gulati-Shapiro test of hypothesis. Supposes that the input data is already ordered.

Specified by:

isFitted in interface FittingAlgorithm

Returns:

true if the data is fitted by the Pareto distribution

isLastRunFitted

public boolean isLastRunFitted()

Specified by:

isLastRunFitted in interface FittingAlgorithm

generateQQPlot

public double[] generateQQPlot()

Specified by:

generateQQPlot in interface FittingAlgorithm
