Betreff: st: Reshaping question
Dear Statalist,
I have a multiple observations per (person) id dataset and a boolean
variable of interest "antibio". I would like to reshape this into a a
single observation per id dataset with a boolean variable indicating
whether the id has one or more observation with antiobio==1.
This is probably an easy task, but I cannot seem to find the right command.
Sincere regards,
Anders Gaarsdal Holst
