Building Quality Assurance for the Occupational Requirements Survey

Randall K. Powers and John L. Eltinge

Abstract

This paper presents a simulation study of some properties of size-based probability sampling with unequal unit-level costs, subject to constraints on aggregate costs. Principal emphasis centers on the distribution of realized sample sizes; and on the distribution of estimation errors for a ratio estimator of per-unit population means.
