For the most part, many users of forest commons...

Does the choice of balance-measure matter under Genetic Matching?

Adeola Oyenubi and Martin Wittenberg
In applied studies, the influence of balance measures on the performance of matching estimators is often taken for granted. This paper considers the performance of different balance measures that have been used in the literature when balance is being optimized. We also propose the use of the...
