Writing a fake Voynich by rules: copies, habits and the link between words

[Jorge_Stolfi]

Anytime you see a horseshoe, it means there is some strict underlying continuous gradient.

Do you see a horseshoe here?  If not, why not?
   

By the way, the word "gradient" means the rate of variation of some quantity Y as function of position X along some direction in some space.  But in the page bigram frequency data there is no Y.  There are just points X scattered in space, possibly clustered into clouds that may be extended in various directions.  Then "elongation" or "spread" would be a more appropriate term.

All the best, --stolfi
