Quote:The statistical properties that we have uncovered in the Voynich Manuscript over the past four posts reveal something of its inner structure. It supports, but cannot prove, that the Manuscript is not a hoax, and that it the text is most likely drawn from some natural language.
The changepoint analyses in this post are a powerful tool for identifying evolution and mutation in data, and the demonstrated example of stylometric analysis to Martorel’s Tirant lo Blanc support their use in revealing points of fracture in texts, without reference to the source language.
With specific relevant to the Voynich Manuscript, both the word frequency changepoint and the topic model changepoint suggest that the manscript’s contents shift significantly at some point around Folios 30 to 40. Given the previous assignment of topics based on manual identification of images accompanying the text, this presents a new avenue of investigation for Voynich researchers.
