I'm trying to fit a path model with a binary outcome, but the observations have simple survey weights (there were no sampling units) and we would like to Bootstrap to test some indirect effects.
I thought I needed to use a weight statement in the Variable chunk, TYPE=COMPLEX and REPSE=BOOTSTRAP in the Model chunk, and specify the MODEL INDIRECT effects. However when I do this I get an error that I need a cluster or strata variable for the replicate weights for the Bootstrap.
I don't have a complex sample with sampling units, so I'm not sure where to go from here. Is there a different TYPE= option for this situation? Is there a way to force the replicate weights be calculated only from my survey weights?
One workaround that "works" is to set STRAT to one of the demographic variables that went into the weights, but this seems like a rough approximation to what we really want to do here.
