you can use the regression method. It gives the robust standard error.
Refer to world bank health equity book
http://web.worldbank.org/WBSITE/EXTERNAL/TOPICS/EXTHEALTHNUTRITIONANDPOPULATION/EXTPAH/0,,contentMDK:20216933~menuPK:400482~pagePK:148956~piPK:216618~theSitePK:400476,00.html
this book has code for standard error.
Thanks,
