Re: st: Interpretation of Log Independent variable
Short answer: for the not-logged var X, you are measuring the marginal increase in odds for a one-unit increase in X at the mean, but for logged var lnX, you are measuring the marginal increase in odds for a 100% increase in X at the mean. Sort of. See http://www.ats.ucla.edu/stat/Stata/faq/oratio.htm and http://www.ats.ucla.edu/STAT/stata/faq/stata_interpret_log.htm for more.
