我用stata做集中曲线,前两步都顺利,最后一步却怎么也不行了;
glcurve perexp,lorenz plot(line rank_invisits rank,legend(label(3 "inpatient visits or not")) || ///
line rank2 rank,legend(label(5 "45 degree line"))) ///
l1 (cumulative share of personal expenture)
graph export Figure1-invisits.emf,replace
在执行“ l1 (cumulative share of personal expenture)”这条命令时,stata提示错误“unrecognized command: l1”,,于是,我就把L后面的1删掉了,以前用这个命令的时候把1删掉还出图了,现在把1删掉,就总提示错误信息说“variable cumulative not found”,,但是cumulative 不是一个单独变量阿,“cumulative share of personal expenture”这是个整体,实在不知道哪里出问题了,,求了解的老师指导!非常感谢~
