Hello Statalists,

I have a question about data merging.

I am merging two data sets together ("master" has tens of variables, and "using" has 8 variables). After merging, one variable from "using" has changed from %10.0g to %9.0g, and a lot of values are missing or changed (no issue for other variables, which are all %10.0g). May I ask what's the reason and how to fix it?

Thanks a lot,
Chenli
