Thank you, Ariel.
I was referring to "cem: Coarsened exact matching in Stata"(by Matthew Blackwell
et.al, The Stata Journal 2009), in which iweight is used usually and aweight is used when
we have multiple imputation. Or has that been changed since 2009? If so, could you please
kindly offer me a reference? I hope I can find out how these weights are used in
estimations.
And I did find two weighting method behave differently. For the same cem_weights, using
pweight or iweight gives different results. I will also try aweight.

I believe an "aweight" is used for cem_weight in Stata, not "iweight".
I think the product of the sampling weight and cem_weight should suffice, assuming the
aweight and pweight don't behave differently...
