A common definition of the law of demand is given in the article The Economics of Demand Zipf's laws are probability distributions on the positive integers which decay algebraically. Such laws have been shown empirically to describe a large class of In NLP, Zipf's Law is a discrete probability distribution that tells you the probability of encountering a word in a given corpus. The input is the rank of a word (in Zipf's Law, Benford's Law. With the view to the eerie but uniform distribution of digits of randomly selected numbers, it comes as a great surprise that, if the Zipf's law is a law about the frequency distribution of words in a language (or in a collection that is large enough so that it is representative of the language).

Zipf’s law, in probability, assertion that the frequencies f of certain events are inversely proportional to their rank r. The law was originally proposed by American linguist George Kingsley Zipf (1902–50) for the frequency of usage of different words in the English language; this frequency is given approximately by f (r) ≅ 0.1/ r. Zipf's law is an empirical law, formulated using mathematical statistics, named after the linguist George Kingsley Zipf, who first proposed it. Zipf's law states that given a large sample of words used, the frequency of any word is inversely proportional to its rank in the frequency table. So word number n has a frequency proportional to 1/ n . Zipf’s Law describes one aspect of the statistical distribution in words in language: if you rank words by their frequency in a sufficiently large collection of texts and then plot the frequency against the rank, you get a logarithmic curve (or, if you graph on a log scale, you get a straight line).
