Perhaps my first blog turned out a little too offensive, just to make it clear, my intentions was not to say that n-1, should not be used. I do to some extent agree (I better do) that if you want to make correct statical calculations, you better use n-1!
But there is also a world beyond that, especially if you work with marketing and customers!

Has the OP been back? I'm appreciative..I'm pleased the statisticians have contributed history, thoughts & experience, good articles and models. Whilst drinking and all! Mikael I have read it you've implicitly highlighted mean (means) and probability, did you mean to?..sorry. I've enjoyed reading and checking-out all these angles so far to discussing n-1

Well my first concern is did we lost the thread starter?


engr.post: "I was just trying to help" lol. Did I really highlight anything (?) cannot find it (thanks for notice and thanks for the editing function).
(After app. 10 years break with real advanced statistics, I properly should never have interfered in this thread, but I was just so thrilled that I actually still could recognize this issue, and remembered that we had this similar discussion, so I still mean it, but the details might be a bit fuzzy).

Still I hope Suresh got a better understanding of Degrees of freedom...
