谢谢
再请教一下,有点没明白。
我没有接触过随机占优这方面的研究。但是,从help文件看,首先data set必须是个complex sampling designed data set.
你如果熟悉complex sampling design的话, 你就知道strata psu weight 的含义和用法了。
domsvy conducts stochastic dominance tests up to order 3 for independent
samples from household surveys who's sampling designs are complex.
Reference is Davidson & Duclos (1998). Confidence level for rejection
of null that distributions are identical is 95 percent (alpha = 5)
Syntax is: domsvy var1 strata1 psu1 weight1
var2 strata2 psu2 weight2
"max poverty line" "# of test points"
Note: Note strata, psu (primary sampling unit) and weight variables must
be included.
