Yules index

Yule's index is a statistical measure that determines the uniformity or diversity of vocabulary. It was developed by the Scottish statistician George Udny Yule and measures the probability with which two randomly selected words in a text are identical - largely regardless of the length of the text. Herdan took up this index and developed it further.
