PROB_KUIPER
Return the significance of the Kuiper statistic
Returns the significance level of an observed value of the Kuiper statistic D for an effective number of data points N_eff. Called by KUIPERONE
prob_kuiper, D, N_eff, probks
D - Kuiper statistic, floating scalar, always non-negative N_eff - Effective number of data points, scalar. For a 2 sided test this is given by (N1*N2)/(N1+N2) where N1 and N2 are the number of points in each data set.
probks - floating scalar between 0 and 1 giving the significance level of the Kuiper statistic. Small values of PROB suggest that the distribution being tested are not the same
