Out-of-sample prediction error for noise peak models. Markers indicate mean values, and bars extend to ± one standard deviation. k=10 out-of-sample prediction errors per dataset were estimated using cross validation. Over the 6 datasets, we obtained 60 values for each model, with: (NP1) Undegraded amplitude model; (NP2) Decayed amplitude model, n=4; (NP3) Decayed amplitude model, n=5
