Hodgson's paradox


 

In statistics and physics, Hodgson's paradox is the observation that the ratio of two Normally distributed random variables has neither mean nor variance, and thus no well-defined expectation. This appears to be inconsistent with conventional views of error estimation. The paradox is named for physicist R. T. Hodgson.
