Hello all,
Can anyone help me understand why imbalance measure for "mat" function is
different from imbalance meausre obtained from matched dataset using
"imbalance" function? Initially when I ran "mat" function, it gave
me
imbalance measure (L1) of
0.727 with 171 matched control and 116 matched treatment. I subset
those matches from the original dataset and ran "imbalance" function
and it gave me L1=0.825
Thank you.
