Out-of-sample prediction error for allelic (true) 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: (TP1) DNA template model; (TP2) Degradation Index model; (TP3) Undegraded, amplitude model; (TP4) and (TP5): Decayed amplitude models with n=4 and n=5 free parameters
