There can't be an explicit function for everything.

That said, the Brier score is the mean squared error of the probability
forecasts
over the verification sample. From Wikipedia

   http://en.wikipedia.org/wiki/Brier_score

    Brier_Score = SUM( (P(n)-X(n))^2 )/N

In NCL

     N = dimsizes(P)
     Brier_Score = sum( (P-X)^2 )/N

Good Luck
