Cui Q1/07 SJ 7(1):141--142 (no commands) tip for graphing several quantities on a continuous axis Chris Witte Subject: Re: st: ci question thanks for the example Svend! I was thinking of doing something like your code, "replace race=race-0.03 if smoke==0 replace race=race+0.03 if smoke==1" for offsetting the plots, and this code will take the error out of my "trial and error" approach to getting the appearance I want. I'll make use of your xlabel code as well! Svend Juul Chris wrote: I would like to know how to take the means and standard errors calculated from the "ci" command, and plot the means with brackets placed at plus/minus the standard error. 1) So, I first need to know how to get these estimates into a dataset for use. 2) I found the "serrbar" command, which will do a basic plotting, but what I'd really like is to have a way to group these estimates, much like the way you can with "graph box" and the "over" option. Is this possible? and later: ... is there a way to horizontally offset the rcap plots within a single x-axis value so that the rcaps do not overlap? =================================================================== I find -statsby- most convenient to extract a condensed dataset with the estimatess of interest. The example also demonstrates a way to horisontally offset the rcaps: webuse lbw.dta, clear statsby mean=r(mean) se=r(se), by(race smoke) clear : ci bwt generate ub = mean + se generate lb = mean - se replace race=race-0.03 if smoke==0 replace race=race+0.03 if smoke==1 twoway (rcap lb ub race)(scatter mean race) , /// xlabel(1 "white" 2 "black" 3 "other") /// ytitle("Birthweight (grams)") /// legend(off) * * For searches and help try: * http://www.stata.com/support/faqs/res/findit.html * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
