The zipf's law
WebThen Zipf's law states that r * Prob(r) = A, where A is a constant which should empirically be determined from the data. In most cases A = 0.1. Zipf's law is not an exact law, but a statistical law and therefore does not hold exactly but only on average (for most words). Taking into account that Prob(r) = freq(r) / N we can rewrite Zipf's law as WebArticle [CPE題庫] in Virtual Judge
