Hello together, In the package 'Matching' there ist a possibility to determine balance statistics after Matching with the function 'MatchBalance'. In this function there has a formula 'formul' to be given. I'm wondering how I can implement all two-way interactions, without specifying them explicitly. For example in logistic regression you can write y ~ (x1 + x2 + x3 + x4 + x5 + ...)^2 and R includes all two-way interactions. Is there such a possibility in 'MatchBalance', too? (Unfortunately, with the notation of logistic regression it doesn't work and I can't find an alternative in the help).
Thank you very much in advance!
