sh_ and ch_ compose the same words

[Torsten]

The correlation between <chedy> and <qokeedy> is therefore even stronger as the correlation between <qokeedy> and <qokedy> or the correlation between <okeedy> and <okedy>.

Pearson's Correlation(chedy[501],  shedy[426]) : +0.84 (n=225)
Pearson's Correlation(qokeedy[305],chedy[501]) : +0.71 (n=225)
...

These are again the absolute values, and it was already demonstrated that these are influenced to a large extent by the variations in the page sizes. It would be more meaningful to give the corrected values.

I would only try to eliminate other factors if I wanted to argue that there is a causal relationship (see You are not allowed to view links. Register or Login to view.).

Anyway, my argument was that there are no 'ch/sh'-word pairs with appreciable negative correlation (see You are not allowed to view links. Register or Login to view.). With other words, it never happens that the 'ch'-variant is typical for Currier A and the 'sh'-variant for Currier B or vice versa. The reason for this result is the shift from Currier A to Currier B.

The following table lists the four most frequent 'ch/sh'-words for different sections:
Herbal A     chol   chor   shol   sho
Pharma A     chol   cheol  chor   cheor
Astro        shey   chol   cheo   chy
Cosmo        chedy  chey   chol   chdy
Herbal B     chedy  chdy   shedy  chkchy
Stars B      chedy  chey   shedy  shey
Biological B shedy  chedy  shey   chey

The top words occur with the following frequencies:
                chol  chor  cheol  cheo  chey  chdy  chedy  shedy   word count
              ------ ----- ------ ----- ----- ----- ------ ------  -----------
Herbal     (A)   228   155     28    14    55     7      1               8,087
Pharma     (A)    45    24     40    11    21     1      1      1        2,529
Astro              8     2      2     5     2     1      4               2,136
Cosmo             19     8      5     2    20    17     24     17        2,691
Herbal     (B)    13     6      6     1    20    53     62     35        3,233
Stars      (B)    62    19     52    30   123    40    190    113       10,673
Biological (B)    14     1     29          94    23    210    247        6,911

The two tables illustrate the shift from 'chol/chor' via 'cheol/cheor', 'cheo/sheo', 'chey/shey' to 'chedy/shedy'. The result of this shift is a "gradual evolution of a single system from state A to state B" (You are not allowed to view links. Register or Login to view., p. 7).

The tables also illustrate the importance of the observations described by Currier: "The principal differences between the two 'languages' in this Section are:
(a) Final 'dy' is very high in Language 'B'; almost non-existent in Language 'A'.
(b) The symbol groups 'chol' and 'chor' are very high in 'A' and often occur repeated; low in 'B'" (You are not allowed to view links. Register or Login to view.).
