@Andy I try to work out what people in the US will be doing, since about half the frequent users are from there. If you throw in Canada... Unfortunately the best time to answer seems to usually be in the very early am on a work-day (my time). I make do.

hi

what can we say about this estimator?

@user2179021, why not ask that on the main site? More people will see it & there are better facilities for providing answers. It isn't really a chat item.

I'm not sure whether this is the best place to ask, but I have put together a tag wiki for skew-normal ( stats.stackexchange.com/tags/skew-normal/info ). This is something I haven't done before and someone better versed than me in what is expected of such entries should probably take a look at it - since tag wikis don't have a "comments" section, there isn't the kind of feedback about whether one is doing right or wrong.
