A R. Hence, we obtain, I p = -log h p = log h p to get a continual h > 0. This base (h) define the unit that we're using. For different h, within the base of logarithm of contagion measure I(p), we are going to get: log 2 units are bits, derived from binary; log 3 units are trits, derived from trinary; log e = ln units are nats, derived from natural logarithm; log 10 units are Hartleys, derived f
