[+/-] Groundhog analysis
Today is Groundhog Day, and Punxsutawney Phil saw his shadow. That means six more weeks of winter, right?
Nope: statistically it means an early spring. The rodent has seen his shadow 94 out of 108 times and been correct 39 percent of the time, suggesting the shadow/no shadow prediction is backwards.
So go have yourself a party! Spring's a commin'!
