They provide the same results in this case as would pweights, were they allowed. Using tabulate with aweights is ok as long as you are only interested in the raw frequency distribution. However, if you are interested interested in test statistics or confidence intervalls or alike, you should think about using, e.g., svytab (type -help svytab-). On pweights, aweights and means, see http://www.stata.com/support/faqs/stat/supweight.html > BTW, is the fweight the inverse of the pweight? No. fweights are frequency weights. They indicate how many times a specific case (i.e. a specific combination of values) occurs in your sample. ben > -----Original Message----- > From: owner-statalist@hsphsun2.harvard.edu > [mailto:owner-statalist@hsphsun2.harvard.edu] On Behalf Of > wying1@umbc.edu > Sent: Wednesday, August 24, 2005 10:23 PM > To: statalist@hsphsun2.harvard.edu > Subject: st: Percent distribution using the pweight > > > Dear list users, > > I want to create the percent distribution (both percent and > frequency are > needed).
