Hello: I tried to add this conversation in an old post, but haven't been able to see much regarding it.
I have seen different descriptions comparing -matchit- and -reclink2-. I saw one Stata presentation on -dtalink-.
Does anyone have an overview on when you would use one of these vs the other and which is better for what type of tasks?
What about with larger data sets, (~500,000 observations)?
-dtalink- seems newer with less information out there...

Thanks!
