How to Use PROC PSMATCH to Match on Age with a Tolerance of 0.1

[YYK273]

Hello SAS Community,

I am working on a project where I need to match subjects based on age using PROC PSMATCH.

However, I require some flexibility in the matching criteria. Specifically, I need to match subjects such that their ages can differ by up to 0.1 years.

I found that the EXACT statement in PROC PSMATCH specifies classification variables to be matched exactly, but this does not meet my requirement for age matching with a small tolerance.

Does anyone know how to implement this in PROC PSMATCH? Any guidance or examples would be greatly appreciated!

Thank you in advance for your help!
