* unique rank for each family member (non-hh head or spouse) based on age 每个家庭成员（非户主或配偶）的年龄的排列
sort hhid
by hhid: egen agerk=rank(nh1b_3), unique, if nh1b_1~=1 & nh1b_1~=2
其中nh1b_3是年龄，后面的if条件表示非户主和配偶。
有哪位高手能告知unique是什么意思？
egen 新变量=rank(老变量），unique, if
这个命令的具体含义是什么？小女子先谢谢了。

唉。
help吧。

rank(exp) [, [field|track|unique]]   (allows by varlist:)  
creates ranks (within varlist) of exp; by default, equal observations are assigned the average rank.  The field option calculates the field rank of exp: the highest value is ranked 1, and there is no correction for ties.  That is, the field rank is 1 + the number of values that are higher.  The track option calculates the track rank of exp:  the lowest value is ranked 1, and there is no correction for ties.  That is, the track rank is 1 + the number of values that are lower.  The unique option calculates the unique rank of exp: values are ranked 1,...,#, and values and ties are broken arbitrarily.  Two values that are tied for second are ranked 2 and 3.

谢谢可爱的版主。
