Thank you Sandu, and more accurately Bill Gould, for this posting. I did not find by searching 'Yatzhaki' but it is, in fact, the Yitzhaki index of relative deprivation of individual affluence (FASt) in a reference group (schoolID): sort schoolID FASt gen sumdiff = . mata: st_view(schoolID=., ., "schoolID") st_view(FASt=., ., "FASt") st_view(sumdiff=., ., "sumdiff") obs = panelsetup(schoolID, 1) for (g=1; g<=rows(obs); g++) { for (i=obs[g,1]; i<=obs[g,2]; i++) { sum = 0 for (j=obs[g,1]; j<=obs[g,2]; j++) { if (FASt[j]>FASt[i]) sum = sum + (FASt[j]-FASt[i]) } sumdiff[i] = sum } } end bysort schoolID: gen Yitz=sumdiff/(_N-1) Frank J Elgar McGill University * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/faqs/resources/statalist-faq/ * http://www.ats.ucla.edu/stat/stata/
