Greetings, I was trying to run the PSMatching under Analyze and when I did that I got an error code as seen below: Errors Subsamples Error Messages (all cases) psmatching3(...): Missing values in dataset. No missing value is allowed in the dataset even when missing in unused variables. But there aren't missing values. I hope someone can help me. Details: SPSS V. 25 R. 3.3.3 PSMatching 3.04 Thanks
