I thought it may be worth a shot, however it is not surprising that -alpha- does not work with -mi estimate-. I guess Stata Corp. documented _every_ official command, that may be used, as the documentation of Stata is usually very detailed. Following the link I provided, and given that Cronbach's alpha can be regarded as "just a point estimate" where Rubin's rules may be applied without correction (maybe someone can comment on this), a starting point might be loc M 5 //replace the number of imputed datasets here sca alpha = 0 mi xeq 1/`M' : alpha bs3c1 bs3c3 bs3c4 bs3c6 bs3c7 bs3c8 bs3c9 if knowlmle<82.6 ; sca alpha = alpha + r(alpha) sca alpha = alpha/`M' di "{txt}alpha : {res}" alpha (I did not run the above, since I have no copy of Stata on the Laptop I am writing this message) Best Daniel * * 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/
