Evaluation of Confidence Interval Methodology for the Occupational Compensation Survey Program

摘要

A theoretical investigation and two simulation studies of the Occupational Compensation Survey Program (OCSP) data, presented by Casady, Dorfman, and Wang (CDW-1994) suggested that the standard 95% confidence intervals (C.I.) for domain means or totals, when based on the standard normal distribution and standard methods of variance estimation, tend to yield less than the actual 95% coverage. Even though the sample size is large enough to support standard normal estimations, the individual occupations are represented by a small number of establishments.
