想请问:
在stata中，如果才能得出panel a,和panel b的结果阿，应该使用哪些公式，在第2个中是否涉及到了rank-sum的公式？求具体方法

非常感谢

panel A	vari 3	vari 4	vari 5	vari 6
size quantile = 1 (smallest)	median	median	median	median
size quintile = 2	median	median	median	median
size quintile =3	median	median	median	median
size quintile =4	median	median	median	median
size quintile =5 largest	median	median	median	median
panel B	var 3	var 4	var 5	var 6
size quantile 1	median	median	median	median
var 2 quantile=1	median	median	median	median
var 2 quantile=2	median	median	median	median
var 2 quantile=3	median	median	median	median
var 2 quantile=4	median	median	median	median
size quantile 2	median	median	median	median
var 2 quantile=1	median	median	median	median
var 2 quantile=2	median	median	median	median
var 2 quantile=3	median	median	median	median
var 2 quantile=4	median	median	median	median
size quantile 3	median	median	median	median
var 2 quantile=1	median	median	median	median
var 2 quantile=2	median	median	median	median
var 2 quantile=3	median	median	median	median
var 2 quantile=4	median	median	median	median
