See help on -egen- or try

egen double x75=pctile(x), p(75) by(group)
bysort group: su x if x>=x75, d
egen double x25=pctile(x), p(25) by(group)
bysort group: su x if x<=x25, d

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
