As a result, when adding CoxSnell R2 to stored results, the wrong N is used for calculation. To quote -help weight-: "iweights have no formal statistical definition; any command that supports iweights will define exactly how they are treated. Usually, they are intended for use by programmers who want to produce a certain computation." So you probably don't want to use iweights anyhow.
