The objective of the present work was to investigate the sampling variability of estimates of the added resistance operator which are made via cross-bi-spectral analysis. The work involved the simulation of large samples from a process similar to that of added resistance, as well as the analysis of these samples. Direct comparisons of the results with the known answer for the simulated process imply that the previously developed methods are correct, but that the required sample of random input and the resulting output needs to be longer than originally assumed.
