Dear Listers,

I want to test the proportion of smokers in four different groups for linear trend (chi2). Usually I solve this using "nptrend" but this time I'm dealing with survey data (and so, sampling weights). How to proceed with this test in this data??? (should I just use logistic regression???) 

Best,  

Rclaro
