caliper - propensity score


I calculated the propensity score per each case in group a and b. I then matched cases manually. How could I calculate (in excel) the caliper I adopted in the matched cohort?

Thank you very much.


Less is more. Stay pure. Stay poor.
Can you add more information in regards to what you are referencing when it comes to caliper. Do you mean the distance and/or criteria for matching?
