tscore {ternvis} | R Documentation |
Calculate the (Brier) score associated with ternary forecasts and observations
Description
A utility function.
Usage
tscore(p, o, L = diag(c(1, 1, 1))/sqrt(2))
Arguments
p |
An n-by-3 matrix of ternary forecasts. |
o |
An n-by-3 matrix of ternary observations. |
L |
A 3-by-3 matrix defining the quadratic score being used. (Default corresponds to Brier score.) |
