Histogram Buckets
Key Histogram Buckets in Model[Simulation] refers to the number N of equidistant intervals into which the range of simulated values is partitioned for the purpose of counting the occurrences that fall in each such interval.
This partition is used to calculate and report an array of N+1 cumulative probabilities and an array of N+1 probability densities that apply at the points defining these intervals.
It also affects the computation of the standard error because the latter depends on the probability density function.
