Isn't plagiarism detection based on overlaps with sentence structure?
That way, it would catch plagiarism if someone simply did a
find-and-replace. But that would also catch regressions with the same
How long was the original thesis? If 25% of it was all regression
output, sounds like a lot of regressions.

If those are somehow factored out, then any R regression could be pretty much identical to any other R regression. However, two analyses with similar variable names could happen if they are based on the same cookbook recipe and analyses with similar numerical output come from analyzing the same standard data. Such situations would not necessarily be considered plagiarism (I mean: If you claim that you are analyzing data from experiments that you yourself have performed, and your numbers are exactly identical to something that has been previously published, then it would be suspect. If you analyze something from public sources, someone else might well have done the same thing.).
> Similarly to John Kane, I think it is necessary to know exactly what sources the text is claimed to be plagiarized from and/or what parts of the text that are being matched by Urkund. If it turns out that Urkund is generating false positives, then this needs to be pointed out to them and to the people basing decisions on it.

There is some caselaw to support the notion that the output alone is not protected in a similar manner, but that may be country specific.
