求指教：ologit回归进行分组检验时，如何利用suest似无相关检验进行组间系数差异检验？我的两组面板数据的具体回归为：ologit y  x1 x2 i.ind i.year , robust cluster( Stkcd ) ,if  z==1
ologit y  x1 x2 i.ind i.year , robust cluster( Stkcd ) ,if  z==0
目的是：比较两组回归模型中x1的回归系数是否具有显著差异

在用help suest时看到有关ologit模型的命令（如下），但！我没看懂svyset psuid [pw=finalwgt], strata(stratid)这一命令的用意以及是否能用于我的数据，相关资料也比较少，所以请教大佬该怎么办？
Example 4: Using suest with survey data, the svy prefix
    . webuse nhanes2f
    . svyset psuid [pw=finalwgt], strata(stratid)
    . svy: ologit health female black age age2
    . estimates store H5
    . gen health3 = clip(health,2,4)
    . svy: ologit health3 female black age age2
    . estimates store H3
    . suest H5 H3
    . test [H5_health=H3_health3]
    . test ([/H5_cut2]=[/H3_cut1]) ([/H5_cut3]=[/H3_cut2])

Example 5: Using suest with survey data, the svy option
    . webuse nhanes2f, clear
    . svyset psuid [pw=finalwgt], strata(stratid)
    . ologit health female black age age2 [iw=finalwgt]
    . estimates store H5
    . gen health3 = clip(health,2,4)
    . ologit health3 female black age age2 [iw=finalwgt]
    . estimates store H3
    . suest H5 H3, svy
    . test [H5_health=H3_health3]
    . test ([/H5_cut2]=[/H3_cut1]) ([/H5_cut3]=[/H3_cut2])
