VPLX: Variance Estimation for Complex Samples

Windows 95/98/NT, Version 1998.09

Version 1998.09 requires at least 16 Meg of RAM and a 486 with a math coprocessor (486 DX ...) or preferably a Pentium or equivalent, running Windows 95, 98 or NT. Because it is a true 32-bit application, the version will not run under Windows 3.1.

The vplx.exe executable was produced by the Microsoft PowerStation 4.0. Users are not required to have this product in order to run the program. VPLX should be installed according to the directions in intra2.pdf. The documentation uses Adobe's Acrobat format, which was described in the section on VPLX documentation.
