- Text Fitness Version 3
This online calculator calculates measure known as fitness score, of how given text is similar to a typical English text. It uses quadgrams (4-grams) statistics to calculate fitness score. Metric is calculated using quadgrams log probability. The statistics is based on Wortschatz text corpus (see http://practicalcryptography.com/cryptanalysis/text-characterisation/quadgrams/). The less value you get, the better.
