Glottochronology (from Attic Greek 'tongue, language' and 'time') is the part of lexicostatistics which involves comparative linguistics and deals with the chronological relationship between languages.

study of the frequency of letters or groups of letters in a ciphertext

subdiscipline of mathematical linguistics that investigates languages using statistical methods to formulate language laws

Stylometry is the application of the study of linguistic style, usually to written language. It has also been applied successfully to music, paintings, chess, and source code.

American statistician (1902–1950)

how often each letter appears on average in a written language

Lexicostatistics is a method of comparative linguistics that involves comparing the percentage of lexical cognates between languages to determine their relationship. Lexicostatistics is related to the comparative method but does not reconstruct a proto-language. It is to be distinguished from glottochronology, which attempts to use lexicostatistical methods to estimate the length of time since two or more languages diverged from a common earlier proto-language. This is merely one application of lexicostatistics, however; other applications of it may not share the assumption of a constant rate
