geoffreycaveney's Judaeo-Greek theory

[MarcoP]

The whole concept of the ambiguation of related groups of phonemes in my letter correspondence table is precisely designed to explain all of the statistical analytical properties of the Voynich MS text that Rene and so many other researchers have studied for decades.

Stating that you are explaining all of the statistical properties of the manuscript is quite bold. Sadly, this generic statement is not accompanied by specific and verifiable measures: quite a contradiction. 
I think the evidence we have suggests that You are not allowed to view links. Register or Login to view. has been designed to give you enough freedom to project Voynichese into Greek words. I see few traces of any awareness of the properties of Voynichese.

I don't claim to cover "all of the statistical analytical properties of the Voynich MS text" but I will only list some broad categories. Your table does not say anything useful about any of them.

Your table actually seems to cause a slight increase in conditional entropy: character sequences are more unpredictable. In Greek (as in basically all languages) vowels and consonants tend to alternate. Your process removes some vowels and has characters that can function as both vowels and consonants: the result is more unpredictability i.e. higher conditional entropy. Even if your table slightly reduces the size of the alphabet, the ambiguation process results in only a small decrease in character entropy. In other words, the transformed text has entropy values close to those of Greek, with a conditional entropy that is marginally higher than the original Greek and much higher than Voynichese.

For instance, the Iliad fragment you considered You are not allowed to view links. Register or Login to view. has
character entropy: 4.10
conditional entropy: 2.45

A Voynich fragment of the same length:
character entropy: 3.77
conditional entropy: 1.68 (much lower than Greek)

If you transform the Iliad fragment according to your table you get something like this (one of an almost infinite number of possible outcomes):

(where C stands for "ch", N for 'iin', S and Z for open/closed "sh")

Entropy values are now:
character entropy: 3.95
conditional entropy: 2.54 (just higher than Greek, much higher than the VMS)

The positional constraints of Voynichese are not only unexplained, they are not even modelled by your table. E.g. the fact that q- typically occurs at the beginning of words. Voynichese word structure is ignored, but for -iin having to occur word finally and -y corresponding to -ς.

Of course, other less obvious features are also totally ignored. E.g. more than 80% of occurrences of q- appear in the form qo-Gallows: why?

This whole phenomenon is not explained (nor modelled) in its entirety.

You are not allowed to view links. Register or Login to view. has shown evidence that refutes the only side of this issue you have discussed (d as a substitute for p/f). BTW, it's interesting that Nablator kindly checked things for you and you didn't even thank him and just ignore his work: so much for "building upon the work of other Voynich researchers." By now I know that my observations here will be hand-waved away with some text-wall devoid of all objective, quantitative data. I should really refrain from wasting my time on this...

A good and simple test for a theory (proposed by You are not allowed to view links. Register or Login to view. and recently mentioned by Farmerjohn) is to check that the most frequent Voynichese words match the most frequent target language (i.e. Greek) words. The You are not allowed to view links. Register or Login to view. you have provided suggests that this is not the case. Actually, you interpret the most frequent words as suffixes / prefixes. Since your system does not (yet) allow  to glue together words that appear as distinct in the manuscript, this also seems like a total failure.

What?

Uh?

I further explored these concepts in another thread, "exercise: 9-phoneme Greek text generation":

You are not allowed to view links. Register or Login to view.

The point is that Greek may be recognizable and readable, albeit with difficulty, even when its phoneme and letter inventory has been condensed into 9 phonemes and 11 letters. This is very much akin to the process that I propose was employed to transform Greek or quasi-Judaeo-Greek into the Voynich script.

No, that is not "very much akin" to the process you propose. That is a small sub-step in your process. Each step in the process throws away some of the information in the original Greek:

• compression of the alphabet (each Greek character mapped into a distinct character)
  
• ambiguation of the alphabet (distinct target characters are replaced by overlapping character sets, with vowels and consonants sometimes mapped into the same character)
  
• joining function words with other words
  
• dropping of vowels
  
• dropping of suffixes
  
• dropping of consecutive identical characters
  

What you say about the first step also applies to the others: each single step makes the text more difficult to read. The combination of all steps makes the text hopelessly ambiguous.
