So suppose I have to use commands like "proc surveyfreq" to get estimates. However, the dependent variable of interest is a dichotomous indicator reflecting rare events (e.g. smoking). For example, only 20 of 20000 students are smokers. I want to see how other factors (e.g. gender) influence the likelihood of being a smoker. Is there any method to deal with this kind of data? If yes, any special issue I should pay attention to? Thank you!</P></BODY></HTML> Tue, 30 Apr 2013 04:33:08 GMT https://communities.sas.com/t5/SAS-Programming/Questions-about-Rare-Events-in-A-Survey-Sample/m-p/124845#M294157 MisoLee 2013-04-30T04:33:08Z Re: Questions about Rare Events in A Survey Sample https://communities.sas.com/t5/SAS-Programming/Questions-about-Rare-Events-in-A-Survey-Sample/m-p/124846#M294158 <HTML><HEAD></HEAD><BODY><P>Surveylogistic or Surveyreg are probably good starting points.
