Adding sampling weights to dsregress

[David Smerdon]

I am attempting to use double-selection lasso regressions on country-level data, where I need to add in sampling weights by country population. How can I include sampling weights in dsregress (or poregress, xporegress)? E.g., is there an equivalent to

reg y x [aweight=myweights]

when trying the command

dsregress y x, controls (mycontrols)

? (If not in-built, how would one add weights manually?)

Did you find a solution for this problem?
