Excerpt: History. This documentation describes VPLX, a general program for variance estimation from complex samples. VPLX was begun in 1989. The initial and continuing objective is to develop a general purpose program for the analysis of survey data generally and Census Bureau products specifically. The program has been used for a number of purposes at the Census Bureau. It is the production system for the variance calculations for the Current Population Survey (CPS), the source of the monthly unemployment rate and other labor force statistics. A number of other researchers have also used the program. It is freely available from the Census Bureau?s web site. This draft marks a renewed effort to document the program. A substantial predecessor draft, which continues to be available, has remained incomplete since 1995. The challenge of explaining the program and experience with users? questions convinced the author that fundamental simplifications in the syntax were required to make the program more accessible.
