One way of doing this is to ensure that -csi- sees the values of the scalars, and not their names. csi `=a1' `=b1' `=c1' `=d1' does that, assuming that none of a1 etc. can be interpreted as variable names. Stata ensures that the expressions given are evaluated before their results are passed to -csi-. Note this short-cut sum stots if heart==1 scalar a1 = r(mean) sum stots if heart==0 scalar b1 = r(mean) sum stotd if heart==1 scalar c1 = r(mean) sum stotd if heart==0 csi `=a1' `=b1' `=c1' `r(mean)' Note, however, that I haven't checked whether there is a way of getting what you want directly from the four variables. Nick n.j.cox@durham.ac.uk Michael Eisenberg I am attempting to create a do file to calculate means of several variables and then use these values in the csi command. sum stots if heart==1 scalar a1 = r(mean) sum stots if heart==0 scalar b1 = r(mean) sum stotd if heart==1 scalar c1 = r(mean) sum stotd if heart==0 scalar d1 = r(mean) csi a1 b1 c1 d1 I get an error that " 'a1' found where integer expected." I'm not sure using scalars is the right way to accomplish this task. Is there a way to use the computed results like r(mean) is immediate commands? If not, can anyone think of a way to do this without having to type in the individual numbers. * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
