If you’re attempting to add pounds, taking a healthy approach is important. Here’s a look at how to gain weight fast and safely.First, frequency weights just indicate how many observations a single observation should count for. If you type --help weight-- Stata will provide a clear defitinon of how frequency weights are considered. fweights, or frequency weights, are weights that indicate the number of duplicated observations.Title stata.com svyset ...

Notice that not using weights is OK as long as the oversampling is exogenous, that is, determined only be the regressors and not by the dependent variable. 2 - Having said that, in case the model is misspecified, using weights is a good idea in that it allows a nice interpretation of the regression results as an approximation to the conditional ...weights must be the same for all observations in a group Each respondent in my data made 3 choices from a set of 3 options (A, B, and status quo) and represents nine observations in the data.
