Method Detail

fitCurve

public void fitCurve(float[] rawDat,
                     double minx,
                     double maxx,
                     javax.swing.JTextArea resultPanelTextArea,
                     boolean rescaleClicked,
                     boolean scaleUp,
                     boolean initReset)

takes data along with x, y limits and fits a pdf to the data range and stores the resulting model fit in data arrays that must be returned by calls to returnModelX() and returnModelY()

generateSamples

public double[] generateSamples(int sampleCount)

generates samples from the distribution and returns a double[] data type

getDescription

public java.lang.String getDescription()

return the description for this modeler

getGraphUpperLimit

public double getGraphUpperLimit()

getGraphLowerLimit

public double getGraphLowerLimit()

getInstructions

public java.lang.String getInstructions()

return the instructions for using this modeler

getKSModelTestString

public java.lang.String getKSModelTestString(java.lang.String distributionModelName,
                                             int numberOfQuantiles,
                                             double[] x,
                                             double[] y)

getKSModelTestString computes the KolmogorovSmirnoff test statistics of the match between the 100 quantiles of the data and their corresponding model-distribution quartile counterparts!

Parameters:

distributionModelName - name of the distribution model-fit

numberOfQuantiles - number of quantiles to use (e.g., 100)

x - data quantiles array

y - model quantiles array

getLowerLimit

public double getLowerLimit()

return the allowable x limit values. This method should return the lower limit. eg: for a normal distribution lowerlimit = NEGATIVE_INFINITY

getModelCount

public int getModelCount()

return the number of models to be plotted. If n models are returned, the vectors from returnModelX and returnModelY will be split into n equal sub sections and plotted

Returns:

getModelType

public int getModelType()

returns one if model is of distribution and needs to be rescaled for display. Returns 0 if model does not require scaling. EG: Polynomial fit is type 0 and normal distribution is type 1.

getResearch

public java.lang.String getResearch()

return the references for this modeler

getUpperLimit

public double getUpperLimit()

return the allowaable x limit values. This method should return the upper limit. eg: for a normal distribution upperlimit = POSITIVE_INFINITY

isContinuous

public boolean isContinuous()

registerObservers

public void registerObservers(ObservableWrapper o)

returnModelX

public double[] returnModelX()

returns the fitted model values for X axis

returnModelY

public double[] returnModelY()

returns the fitted densisty for corresponding X axis values

useInitButton

public boolean useInitButton()
