Dear Friends,
I'm using Matchit package for a Cohor Study.
After match the number provided by the summary output apparently don't
correspond to the true value:
Here the values provided by summary:>summary (test) Summary of Balance for
Matched Data Age: Means treated 44.89; Means control 45.47
However, after applying a test (for instance) I get:
mean in group control: 47.47 and for treated group: 44.89
Why the means differ between this 2 functions (summary and t-test)? Am I
missing anything about the means generated by the summary command after
match?There is no missing data.
Thank you in advance for your help and patience.
Please provide the code and a toy example so that we know what you
actually did. Otherwise it is hard to help.
Best,
Uwe Ligges
