A better approch?

In Response To: A better approch? (eXtreme Gammon)

I think we've discussed something similar a while ago on this forum (too lazy to search back).

I proposed something like: for each move but the top one, show a % indicating the chances for the move to be better than the top one (that's a simple translation of the jsd criteria into %). BTW, as already noted by many, that's a single-tail confidence interval, not a double-tail one.

Despite not giving the full statistical picture (since what you really want to know is the chances for *at least one* of the non-top moves to be better than the top one, or equivalently the chances for the top move to be better than *all* the other ones) it is extremely easy to understant for non-stat guys.

Then one of your stopping criteria could be: stop when no move has more than x% chances of being better than the top one.

Also, I'm in favor of coupling stop criteria, someting like stop when:

- no move has more than x% chances of being better than the top one, AND - std dev of each move is below y points (EMG).

2nd one grants each move has been rolled out enough to have a decent estimate, 1st one capture the global picture (across all the moves).

MaX.

P.S. Just like Bob, Iùve always considered the independence assumption as very suspect.
