Hi all,

I have a file set up as follows

coname	mcap	btom	trade
A		35	.6	1
B		30	.1	0
C		32	.4	0
D		45	.3	0
E		56	.45	0
F		75	.23	0
G		26	.43	0
H		47	.35	0
I		25	.9	0

How can I use the propensity score matching technique to match the firms
for which trade=0 with firm for which trade=1, in terms of mcap and
btom?

Thanks
rajesh
