hi Jason, I thinks it really hinges on if the 5% sample and the extra
samples are acquired under the same
survey design. If this is true, you can generate the same weight using the
method applied in the 5% sample.
If not, then you should not try to impute any weights since different
surveys have different designs and we can't compare
an apple with an orange.
