Globally Robust Inference
... standard asymptotic theory generally require assumptions of symmetric error distribution or alternatively known scale. None of these assumptions are met in most practical problems where robust methods are needed. One alternative approach for estimating the sampling variability is to bootstrap a robu ...

STATISTICS and PROBABILITY
... A discrete random variable is a rv with a finite (or countably infinite) range. They are usually integer counts, e.g., number of errors or number of bit errors per 100,000 transmitted (rate). The ends of the range of rv values may be finite (0 ≤ x ≤ 5) or infinite (x ≥ 0). ...
