cTTO composite time trade-off, MAE mean absolute error, RMSE root mean square error

MAE and RMSE of three different anchoring techniques; linear mapping, linear mapping without a constant and rescaling directly on the mean observed value for state 33333 in the cTTO data. MAEs/RMSEs are calculated on the mean cTTO values for the 28 health states in the health state design (fourth/sixth row) and the means for the mild health states, which have at most one level 3 or two level 2 problems (fifth/seventh row)
