1. Pool 2. Divide weights by four (would affect only totals, but still a good idea) 3. -svyset- the whole thing.

Or should I rather use -svyset- for each of the 4 datasets, pool them in one, and then divide the weights by 4? Further, sorry for bothering you: what are PSUs? How do I check if they change form year to year? -- Ivica Rubil Ekonomski institut / The Institute of Economics, Zagreb Trg J. F.

If the PSUs did not change over the four years, then treat the pooled sample as one large sample, and use the same -svyset- statement that you would use for a single year. If some PSUs changed you will have to do some stratum recoding. For an example see http://www.cdc.gov/nchs/ppt/nchs2010/46_Moriarity.ppt Steve On Sep 26, 2011, at 12:03 PM, Ivica Rubil wrote: Dear all, I am trying to pool four repeated cross-sections of Croatian Hpusehold Budget Survey. For each year that I want to pool, I have sampling weights for each observation (both household and person). My questions are: What should I do with the weights once I pool the four datasets? Is it wrong to use dataset-specific weights in the pooled dataset and just run estimation commands with the weight option, if available? I am confused. Please, help.
