I'm not very clear with the aim of Nick's research, but, as far as the above
reported sentence in concerned, Nick might want to try: 
--------------------------------------------------------------------
set obs 10
g id=_n
g child_1=1 in 2/6
replace  child_1=0 if  child_1==.
g child_2=1 in 7/8
replace   child_2=0 if   child_2==.
g child_3=1 in 9/10
replace   child_3=0 if   child_3==.
egen grand_child=rowtotal( child_1 child_2 child_3)
-------------------------------------------------------------------
Kind Regards,
Carlo

Oggetto: st: combine indicator values
Hi to all.
I have the following binary (0,1) variables:
child1, child2 child3
They indicate if the family has or not 1, 2, 3+ children respectively.
I would like to enter them in a logistic model using the xi commnad and
child1 as reference, after I combined them into 1 variable.
Any advise would be appreciated.
Many thanks,
Nick
