Abstract The purpose of this paper is to study and compare the methods for constructing confidence intervals variance components in an unbalanced one-way random effects model. are based on a classical exact, generalised pivotal quantity, fiducial inference quantity. comparison criteria involves empirical coverage probability that maintains at nominal level 0.95 shortest average length interval....

Monte Carlo criticality simulations are widely used in nuclear safety demonstrations, as they offer an arbitrarily precise estimation of global and local tallies while making very few assumptions. However, since the inception such numerical approaches, it is well known that bias might affect both errors on these themselves. In particular, stochastic modeling approaches developed past decade hav...
