Document

For a random variable X whose values are distributed according to this distribution, this method returns P(X = x).

Usage

From source file:geogebra.kernel.statistics.AlgoZipf.java

protected final void compute() {

    if (input[0].isDefined() && input[1].isDefined() && input[2].isDefined()) {
        int param = (int) a.getDouble();
        double param2 = b.getDouble();
        double val = c.getDouble();
        try {// w ww.ja v  a 2s . com
            ZipfDistribution dist = getZipfDistribution(param, param2);
            if (isCumulative.getBoolean())
                num.setValue(dist.cumulativeProbability(val)); // P(X <= val)
            else
                num.setValue(dist.probability(val)); // P(X = val)

        } catch (Exception e) {
