Zipfs law is a discrete distribution related to the Pareto distribution. If X has a Zipfs law

Question:

Zipf€™s law is a discrete related to the Pareto If X has a Zipf€™s law with parameters s > 0 and n ˆˆ {1, 2, . . .}, then

1/k P(X = k) = for k = 1, ...,7 n. E(1/i8)'

The distribution is used to model frequencies of words in languages.
(a) Show that Zipf€™s law is scale-invariant.
(b) Assume there are a million words in the English language and word frequencies follow Zipf€™s law with s = 1. The three most frequently occurring words are, in order, €œthe,€ €œof,€ and €œand.€ What does Zipf€™s law predict for their relative frequencies?
