help for an economic student thesis

[lor cap]

sorry but I need help to work with stata and I'm very new to this software. For my thesis I would like to calculate the degree of similarity in economic cycles across South American countries using data from GDP.
how can I do that?
thanks for the help

Due to their broadness and vagueness, this kind of questions are doomed to be left unreplied.
Please see the FAQ on how to post (more) effectvely. Thanks.
