			20, 20 + noItems - 1);
	final LogNormalDistribution probDist = new LogNormalDistribution(
			new Well19937c(1), mu, sigma);

	while (backgroundItemsets.size() < noItemsets) {
		final int len = sizeDist.sample() + 1; // use shifted geometric
		final Itemset set = new Itemset();
		for (int i = 0; i < len; i++) {
			final int samp = itemDist.sample();
			set.add(samp);
