[Article] "Principal component analysis of characters in the Voynich manuscript

If you use frequencies instead of log frequencies, you get plots like this: You are not allowed to view links. Register or Login to view..   This loses information, though, and vowels no longer cleanly separate from consonants.   So if he did get a clean separation, I suppose he must have used log frequencies.  Similarly shaped VMS glyphs do indeed cluster together, but shapes in European alphabets don't particularly match pronunciation or other phonetic features (unlike, say, those in Hangeul).   This itself is an interesting observation, suggesting that whoever devised the script might have taken phonetics into account.   I'd like to read Jonas Alin's paper but I don't have access to Cryptologia.
