Hi

I am cleanning a music dataset and one of the problems I have is that
there are many cases in which there two different origin countries for
the same artist. For instance, Shakira appears as from USA, Colombia,
Netherlands and UK.

I want to assign one unique origin country to each artist based on the
number of records. I have 94,330,173 observations, so I can't do it
manually.

My problem is that I don't know how to tell Stata that I want to see
those cases in which there are different countries for the same
artist. Both are string variables. Once I identify those
"wrong"observations,  I would select one unique country for each
artist according to the number of Total sales, which is numerical
variable

Any idea?

Thanks in advance,
Estrella
