In the first setting, an artificial word was added to one segment of both the target and comparison corpus. This setting enables us to analyze the influence of only one parameter, namely the frequency. To maintain a constant total word count while adding an artificial word, other words in the corpus that occupied the same position as the artificial word were replaced. The frequency of the artificial word was constant (10 words) in the comparison corpus, but varied in the target corpus (10 to 2000 words). <hi xmlns="http://www.tei-c.org/ns/1.0" rend="italic">Pydistinto</hi> was run 100 times for each of 12 frequency settings, to mitigate the occasional impact on the results of high scores for frequent words. The corpus was randomly divided into target and comparison parts for each run. Given the fact that texts were built by randomly sampling words from the entire corpus, any difference between the target and comparison corpora, apart from the artificial word, can only be due to random variation.
