Hi all.

Wish you all well.

I have to do weighting for an alcohol longitudinal study(2011-2013).
How do I go about getting the final weights?
Some people stopped responding as the survey progressed leaving only the drinkers responded in the end(2013).
Does it sound statistically right by multiplying the sampling weights with postratification weights(weighted on census by gender, age and ethnicity) then by attrition weights to get the final weights?

Any input will be greatly appreciated
