I am a new user of sas. I wanna test the interval validation, so I use proc surveyselect for bootstrap resampling. Below is my codes: sasfile g load; proc surveyselect data=g out=gg seed=123456 rep=1000 method=urs samprate=1 outhits; run; sasfile g close; proc surveylogistic data=gg ; model y(descending) = exposure; run; However, from proc surveylogistic I got a ridiculous confidence interval of exposure: (OR=1.2, 95%CI:1.2-1.2). I mean, after getting 1000 times replications, the sample size increased and the CI seemed too small.. But I used the method of unrestricted sampling without weighting, so I don't how to get the plausible standard error to estimate CI. How to deal with that? Can anyone help? Thanks very very much~~!!
