wilson

public static double[] wilson(int total,
              int correct)

Computes the Wilson Interval (see http://en.wikipedia.org/wiki/Binomial_proportion_confidence_interval#Wilson_score_interval) Given the total number of events and the number of "correct" events, returns in a double-array in the first component the center of the Wilson interval and in the second component the width of the interval. alpha=95%.

public static double[] confidenceInterval95(int mean1,
                            int mean2)

Calculates the 95% confidence interval for the ratio of the two menas.

Parameters:

mean1 - mean 1

mean2 - mean 2

Returns:

array containing the low and high values of the interval
