Need advice for testing of hypotheses related to the self-citation method

[Mauro]

Not exactly what you asked for, but while reading your post above it came to my mind a procedure which could be tried, as a first step.

Thanks, but I already wrote the program to count patterns of type 1a, 1b, 2a, 2b in each page a few months ago. Now I am looking for something to do next.

I'm not sure I understand what you mean by 1a, 1b, etc. but it looks interesting. Did you post the results? I may have missed the thread.
