Note(s): Ten-fold PLSpredict with ten repetitions. Values are averages across the indicators belonging to each outcome. LM = linear-model benchmark; ΔRMSE = PLS RMSE minus LM RMSE, so negative values favour PLS. The final column reports the number of indicators for which PLS produced a lower RMSE than the benchmark
