A Proper Scoring Rule for Confidence Intervals

Is there a way to adjust this to support better scores for tighter confidence intervals?

For instance, using natural log, with a range of 8-10 and a true value of 10, I get -0.2231 whether I pick a 90% confidence interval, or a 95% confidence interval (coefficient of 40). It'd be nice if the latter scored better.

Lotteries: A Waste of Hope

For powerball to have an Expected Value of 1, the individual take-home jackpot would have to be about $313,124,412 for the lump sum, after taxes. (Which, assuming average state income tax rates, corresponds to an advertised jackpot of roughly $805,000,000 AND assumes the jackpot doesn't have multiple winners, which at that level is pretty unlikely.) Of course, since it's a risky bet, you don't want to blow your whole bankroll on lottery tickets even if the EV is above 1. That's where the Kelly Criterion comes in.

I had originally suggested that she ask him ahead of time something like, "well if we do this test and it comes back clean, will you let it go?" but he wasn't even open to the question.

Like what? Just curious.
