Problem with the MatchBy function

[tejendrapsingh]

Looks like the GenMatch function called by the Matchby function has some issues. I am posting the code and the associated error below. Thanks.

Code:
set.seed(12345)
rr <- Matching::Matchby(#Y = Y,
Tr = Tr, X = my.X, by = by1, M = 1, replace = TRUE, estimand = "ATT", ties = FALSE)

Error Message:
60 of 5106 groups
Error in if (Sig.X[k, 1] < tolerance) Sig.X[k, 1] <- tolerance : missing value where TRUE/FALSE needed In addition: Warning message: In sqrt(max(tolerance, sum(X[, k] * X[, k] * weights))/weights.sum - : NaNs produced

Hi did you fix this issue? I ran into the exact error with you and I have no idea how to solve this, too.

I think are no valid matches for some subgroups.

Did you remove the subgroup in order to do this? On Wed, Jul 20, 2022 at 19:13 Jasjeet Sekhon ***@***.***> wrote:
