The mainstream paradigm theory for the chronology of the appearance of these manuscripts in antiquity is during the period (approximately) 125-425 CE.

I seek to establish an alternate theory in which proposes these manuscripts appeared during the period (approximately) 325-425 CE

Some time ago I attempted to conduct a chi squared test on the data by considering two chronological "buckets" 125-324 and 325-424

You will find this here: Weighing the chronology of the Gnostic "page counts" > 325 CE (mountainman.com.au)

If you have any comments, questions, criticisms, observations --- please post.

I have been given advice that the application of a chi squared test is not appropriate here because the the survival rate of manuscripts from antiquity is not a random variable. Now - quite obviously the more centuries we go back the less historians find. The variable, it was claimed, was unknown, but not random. I was advised to make a study of the general survival rate of manuscripts over time. And then apply this to the analysis. But I have nagging doubts that it is entirely reasonable to use a chi squared test and examine the weighting between the two chronological "buckets".

I hope this question is relevant for discussion in this forum.

Otherwise any other advice would be appreciated.

Thanks.
