tsetup function

Utility function to calculate geometry associated with a quadratic score matrix

This is just a useful internal function.

tsetup(L = diag(c(1, 1, 1))/sqrt(2), q = cbind(1, 1, 1)/3)

Arguments

• L: A 3-by-3 matrix defining the quadratic score being used. (Default corresponds to Brier score.)
• q: A 1-by-3 matrix containing the climatology.
