(a) Hysteresis loop M(H) and a set of five recoil curves obtained by reversing the applied field at distances , from saturation. (b) -data calculated as field differences between the recoil curves 1–5 and the decreasing major hysteresis loop branch.

(a) The elliptical region corresponds to reference functions indistinguishable in the 95%-confidence-level statistics sense from input data corresponding to and . (b) The stripe region is obtained when only major loop data and H(M) are used as the reference and input functions. (c) The dot corresponds to the unique reference function agreeing with the input data . The crossing point of the dashed lines shows location of the reference function chosen as the input data set. The slope of the pattern in (a) is and in (b) is .

[(a)–(c)] , , and parameters estimated from the data obtained from the hysteron model. Large error bars in (b) and (c) mean that interactions cannot be determined within any reasonable confidence. Small error bars in (a) show uniqueness with respect to . [(d)–(f)] The same analysis for the combined -method demonstrating unique identification of all model parameters.
