Greetings!
The -merge- command in Stata requires that the variable to merge
uniquely identify observations in the master dataset. But how should
I merge if the variable I would like to merge on does not uniquely
identify master dataset observations?
For instance:
Master: ID GROUP
(multiple IDs could be in the same group)
Using dataset: GROUP GROUPDEMOGRAPHICS
I wanted to do
.merge GROUP using ..., sort
error message r(459): something that should be true of your data is not;
My final dataset should have each ID as an observation. Is there
something I can do to work around this?
Thank you!
