Hi all,

I'm using the svy command to analyze a 2-stage stratified complex data and am trying to do a lowess smoothing plot for my continuous against the outcome to see if I need to make splines for my model.  However, lowess is not supported by the svy command.  Someone has suggested using the "expand" option to get the inverse of the individual weights to create a weighted lowess plot.  However, because individual weights are not providing in this public dataset (I'm using  jackknife variance estimation method with the following command :svyset [pw=rakedw0], jkrw(rakedw1-rakedw80, multiplier(1)) vce(jack) mse) to run my svy analysis, I cannot use that method either.   There are too many observations in my dataset to simply do a scatterplot without smoothing, does anyone know of other ways to conduct exploratory data analysis on continuous covariates against outcome to look for splines using the svy command?

Thanks so much!
