st: How to do percentage analysis

["Maoyong Fan" <fan@berkeley.edu>]

Dear Friends,

	I have a dataset like this:

hhid	group     
104	       0  
201	       0  
108	       0  
107	       0  
103	       1  
109	       1  
106	       1  
105	       1  
102	       1  

For each group (0 and 1), I want to get the mean/median/s.d. of top 25 quantile obs and mean/median/s.d. of bottom 25 quantile obs.   

How could I do this in Stata?
	

Warm regards,

Maoyong
