Interpreting the Imposter score's confidence

[Frédéric Tomas]

Hi all,

I am currently working on a cyberbullying case relying on the General Imposter framework. I have computed my imposter score for the candidate and anonymous text compared to the imposters, and it is .61.

After 5 long hours of running, the optimization of the imposter function gave me p1 = .44, and p2 = .49, which tends to support the hypothesis that my candidate would be the author of the anonymous document "with a high degree of confidence" according to the CS imposters page.

But what does a high degree of confidence actually mean in this case? Is there any quantitative way to determine this?

I would really appreciate anyone's help on this matter :)

Thanks!

Frédéric
