bob and all those who have been asking similar questions:

yes, the skeleton program for computing alpha that i have so far
will eventually have various unique features. i am saying
"unique" with some confidence as the extension of the well known
formula for alpha (for many coders, any metric, missing data,
etc.) required quite extensive mathematical work, completed a
couple of years ago, for example, for the computation of:

 

* confidence intervals

* the probability of failure to achieve a required level of reliability

* the reliability for individual coders

* the accuracy of coders (relative to a known standard)
as distinct from reliability

* the reliability for partitions of units of analysis, comparing different
classes of units with each other

* the reliability of conditional variables, variables that
depend on what happened on another variable

* the reliability for situations in which one unit of analysis is
assigned to multiple values, not one

* the reliability for unitizing, for example of textual matter.
and more.
i do not know of any other agreement coefficient that is capable of answering these
questions.

normand peladeaui of provalis research, known as the creator and
owner of wordstat, is programming the software. progress is slow
but normand has written more complex content analysis software in
the past, as we all know, and he intends to bring the project to
fruition soon.

unfortunately, i cannot give you a definite date of completion.
if you continue to be interested, ask me in a few months for a
progress report. thanks for your continued interest.

In a recent e-mail Klaus Krippendorff referred to a skeleton
program that researchers have used for the purpose of computing
content analysis reliability.

I would be interested to know if this program has any additional
features to other programs that are available and an indication
of when the program might be available.

Any assisatnce with the above is appreciated,

regards

Bob green
