I am disturbed to see that the great-grandparent of this comment (the one saying "that doesn't make sense for a Bernoulli variable) has attracted 5 new upvotes since the parent of this comment (the one saying "oops, that was a mistake") was posted.

Everybody: Please stop upvoting my wrong comment. It was wrong. At best it may suggest a lack of clarity in the comment it was replying to, but that doesn't deserve 10 upvotes.

Thank you.

(Not that I mind being upvoted as such, but I do wish I saw more correlation between the quality of my comments and the votes they attract.)
