I'm appreciative of Mullen's posted comments. This is lots better

than trying to converse through a printing press.

It sounds like we have some impediments to communication tripping us up.

One is the word "Caesarean". After careful reading, I still see

Mullen arguing (effectively) in his book that within the Gospel of Mark

Theta + 565 + Orig + Eus + (700 + CyrilJ) are in fact related to each other.

The traditional name for this grouping is either "Caesarean" or

"family Theta", without any requirement to buy into all of Streeter's theories

or to inflate the group into a many-tentacled I text type.

Mullen's point that p45, W, f1, et al do not belong to this small group,

even in Mark, is appreciated.

Perhaps the name Caesarean has too much connotational baggage attached.

Colwell's metric on witnesses is a good first step in scoping out the

lay of the land. This, however is not the situation of the Cyril book.

I saw the goal of the book to be placing Cyril's text among the

already known text types and textual landmarks. The tables labeled

"Cyril's Percentages of Agreement with Control Witnesses in <book>"

were indeed presented in advance of Ehrman's profiles, but I didn't

observe any case in which those tables told us anything about

Cyril's affinity to text types that wasn't later visible in the profiles.

I would enjoy learning of counterexamples.

But the concept of a (possibly indistinct and non-independent) text which can

be traced through time in Palestine is presupposed by the numerous

comments made in the book about "shifts", "moving", "evolution",

"trajectories", "transitional", et al. Such expressions don't make a lot

of sense without some kind of cause/effect relationship connecting the

Palestinian patristic texts through time.

employed as an initial approximation. One should, more generally,

be able to estimate the degree of relevance a witness has to

the voting issue at hand. With more analysis, some kind of second-order

voting scheme ought to be possible that mitigates the problems due

to the nonindependence and the biased survival chances of family members.

If internal evidence and local genealogy tell us about the direction

of textual change, then nonsymmetric voting rules could come into play.

to speed the computation, and it fails for small N and p near 0 or 1.

It may help to explain that the "plus/minus 3.18" somethings is supposed

to represent a "confidence interval" for the estimate. The observed agreement

count is an integer from 0 .. N, while the unknown parameter is

the agreement level p, a real number in [0,1]. A 95% confidence interval

is a mapping from observations to intervals for which the probability

of the interval containing the true value of p is always at least 95%,

but the length of the intervals being minimized for economy (and uniqueness).

The critical factor for choosing sample sizes is the smallness of the

confidence intervals around your results that you need.

In our situation, we are comparing the agreement of Cyril with witness X

against the agreement of Cyril with witness Y, and *Cyril* is the

random variable, while the control witnesses are the fixed quantities.

So, the two agreement counts Cyr/X and Cyr/Y are each binomials,

but not independent binomials.

The difference in agreement counts depends only on how Cyril reads

at the points of variation where X and Y *differ*. That might be some

kind of shifted binomial, with a different N.

About decimal points... the number of digits you quote doesn't depend

on precedent in the field, it depends on how accurate the datum is.

It is good practice to write down only "significant" digits.
