Thank you Nick, I think I should try another strategy then. And btw, yes I did ask the same question several days ago and didn't get any response, so I am anxious then. -----邮件原件----- 发件人: owner-statalist@hsphsun2.harvard.edu [mailto:owner-statalist@hsphsun2.harvard.edu] 代表 Rubi Lam 发送时间: 2014年3月12日 星期三 20:05 收件人: statalist@hsphsun2.harvard.edu 主题: st: Combine several variables into one Hi fellows! I am now writing an essay about the relation between personal income and health status, and have already collected enough questionnaire. There are few questions related to the health status like how much did you spend on the sickness or how many days are you absent from work due to the sickness. Now I need to mix them up to create a new single variables to represent the level of health status. I've tried pca and factor, neither of them worked out since the variables didn't lessen or the uniqueness is so big that the factors didn't explain enough information. Therefore I do need you help to work it out by a new method that is doable in stata12. Many thanks to y'all! Have a nice day!
