Method Detail

getDensityAtStdDev

public static double getDensityAtStdDev(int stdDev)

getDensityAtStdDevBin

public static double getDensityAtStdDevBin(int stdev)

Get the density over the curve in the interval [stdev-stdev+1[

Parameters:

stdev - the standard deviation interval to compute the density in.

Returns:

a density value [0, 1[.

getIntervalAreas

public static double[] getIntervalAreas(double area)

Return a list of areas for 12 sigma intervals from [-6, -5[ to [5, 6[.

Parameters:

area - the area of the data.

Returns:

a list of areas where there sum is equals to area.
