testGaussianCase

public void testGaussianCase()

If alpha = 2, than it must be Gaussian distribution

testCauchyCase

public void testCauchyCase()

If alpha = 1, than it must be Cauchy distribution

testAlphaRangeBelowZero

public void testAlphaRangeBelowZero()

Input parameter range tests

testAlphaRangeAboveTwo

public void testAlphaRangeAboveTwo()

testBetaRangeBelowMinusOne

public void testBetaRangeBelowMinusOne()

testBetaRangeAboveOne

public void testBetaRangeAboveOne()
