Dear all, 
I have a variable that identifies the household (hid), a variable that
identifies the number that each individual has within the household
(pid) and finally a variable that has some values of interest (present
only for some individuals).
I would like to create a new variable (var2) that has the value of var1
for all the pid in the same hid (as in the example below).
hid	pid	var1	var2        
1	1	10	10           
1	2		10               
2	1		6              
2	2	6	6            
2	3	6	6             
2	4		6              
3	4	8	8                 
3	5		8	               
One way to do it is:  
by hid: egen var2=mean(var1)   
However, I was wondering if there was any command that rather than
taking averages, could copy that value to everybody with the same hid.
Thank you
Manos
