 ```***** To join INSNA, visit http://www.insna.org ***** Hello Andrea, The "proportion as large" is the proportion of random permuted samples that had a statistic (like the E-I index) as large as the one observed in your actual data. It is the exact "p-level" of the statistic -- or the probability that your observed statistic (or a bigger one) would be observed if a random process was generating the data. Robert A.
