Computation of an empirical p -value for the TI and NTI. An empirical p-value for the TI (as well as for the NTI) is obtained using a Monte Carlo simulation: A TI is computed r ≥ 10000 for the same clustered tree but randomly permuted labels. The p-value is defined by the fraction of TIs that is equal or higher than the TI obtained from the original label and cluster tree (here: p =18.46%). The resulting p-value of 0.1846 ≥ 0.05 indicates that there is no significant correlation between the clustered data and the label.
