V6094 The expression was implicitly cast from 'int' type to 'double' type. Consider utilizing an explicit type cast to avoid the loss of a fractional part. An example: double A = (double)(X) / Y;. ProbabilityWeightedMoments.java(130)

public static <A> double[] alphaBetaPWM(...., final int nmom) {
    final int n = adapter.size(data);
    final double[] xmom = new double[nmom << 1];
    double aweight = 1. / n, bweight = aweight;
    for(int i = 0; i < n; i++) {
        ....
        for(int j = 1, k = 2; j < nmom; j++, k += 2) {
            xmom[k + 1] += val * (aweight *= (n - i - j + 1) / (n - j + 1));
            xmom[k + 1] += val * (bweight *= (i - j + 1) / (n - j + 1));
