Description:

The question was once asked of me, "Why square anything?", made in reference to the Brier Score (BS) used in Probability of Precipitation forecast verification. There is a fairly simple way of showing how the Brier Score works and why it has been used all these years. The following development is similar to that given in the explanation of why the BS is a "proper" scoring system according to Murphy and Epstein (1967).
