not really, most of them only fail skew/kurtosis, but not all, and they fail different tests in different combinations. Sure, this can be differentiated, but I'd suggest doing it a bit differently. Like I was saying, remove one distribution from the list, fix the problems, make it a PR. Repeat. I've fixes for a good part of this list already :-). There are tougher nuts (`ncf` for one), and when we're doing to just a few which fail, then it'll make sense to mark specific tests. How does that sound?
