Hello - I’m looking at cross-sectional trends in food insecurity data. From 2001 to 2009, there are no replicate weights. Then there are 145 replicate weights from 2010-2013, then 160 for 2014 onward.

If I calculate trends asking STATA to use replicate weights when they’re only available for some years, the coefficient of variance balloons for those years without 160 replicate weights (understandably).

Should I:

a) create my own brr replicate weights for 2001 to 2009? What would I do for 2010-2013?

or b) do my analysis without using the replicate weights? If that’s the case, would I just use Taylor linearized variance estimation? Is there something else I should put in the svyset command to control for the survey design? I understood that the replicate weights were a way of accounting for the strata / cluster design since we don’t have those variables

Thank you!
