Monte Carlo (MC) explorations of likely parameter values under different assumptions about the number of definable components have been reported to gain insight into the best ways to evaluate multicomponent exponential decay data. In this report, MC is used to validate and illuminate predictions of ARM+LSQ analysis with component selection heuristics. The approach can also help describe parameter uncertainties. To explore this, a decay curve was created using the starting distribution shown in Figure , and Gaussian random noise was added to the level of 0.3% of the first point.
