Estimates the number of clusters as the number of big merges + 1. The probability threshold is an adjustment that renders this estimation process more robust to sampling fluctuations. If the sum of the sample frequencies for the two merging clusters in the last big merge is less than 50 percent, we do not report any merges and thus are left with just 1 cluster. See the referenced paper for more details.
