Dear listers,
I would like to carry out some matching for a case-control study using
STATA but its proving to be a bit challenging to me. I have checked
from achieves but a query close to mine on statlist was not answered
in 2004. Could there be a way of matching cases to controls within a
range of values say for age, a 40yr old case-patient can be matched to
either a 38 or 39 or 40 or 41 or 42yr old control-patient? I have used
the -merge- command to merge two datasets by sex and age of patients
but it only works for 40yr old case matching a 40yr old control. For
this case am still interested in a 1-1 matching but what if I extend
this to a 1:n match? I want to have something of this sort:
case-patient case-age sex
control-patient control-age
1 00b7 35 1
00YP 35
2 00b7 35 1
0XC1 33
3 00b7 35 1
0001 36
Any suggestions.
Henry
