Subject   st: Use of weights from Current Population Survey, March Supplement
Date   Thu, 15 Apr 2010 10:51:56 -0500

I am using Stata 11.0 to analyze the Current Population Survey.
Specifically, weights on this survey are nonintegers, therefore when
using frequency weigths - fw=marsupwt- sends the following message:
may not use noninteger frequency weights.

I came out with two options, but which should I used? and Why?

1. To use the importance weight -iw=marsupwt-, which allows the use of
noninteger values, or
2. To generate a new weight, rounded to the nearest integer and that
for those values that are negatives, values are set to zero.

Any recommendations about the use of either option? Thanks!
