#> The SFO model is rejected as S_SFO is equal or higher than the critical value S_c
#> The representative half-life of the IORE model is longer than the one corresponding to the terminal degradation rate found with the DFOP model.
#> The reprentative half-life obtained from the DFOP model may be used
