Success rate and goodness of fits with the CHA ^x models. 1,000 fits with de novo generated data points each were performed with each model. The start vector consisted of the true values. The value n indicates the number of successful_p fits out of 1,000 fits. (A)n of successful_p fits out of 1,000 fits. (B) Mean inaccuracy, miac_np,n, computed over all n_p parameters according to Eq. 15. (C) Mean imprecision, mipr_np,n, computed over all n_p parameters according to Eq. 12. (D) Mean absolute correlation coefficients (see Materials and methods). The influence of the different signs was abolished by taking their absolute values. Also, the “1” of the main diagonal was taken out. n specifies the number of included successful fits.
