How to generate counts

[Amber Pong]

I have a dataset that shows different providers that participated in studies at different hospitals. The variables are: id, name, hospital, type. I'm trying to generate the number and percentage of hospitals that participated by the type and also the number and percentage of unique hospitals that participated by the type. Here is an example dataset:

Something like this:

split hospital, parse(";") gen(hosp)
reshape long hosp, i(id)

//  TABULATION OF HOSPITALS BY INTERVENTION TYPE
tab type

//  TABULATION OF DISTINCT HOSPITALS BY INTERVENTION TYPE
egen flag = tag(type hosp)
tab type if flag

In the future, when showing data examples, please use the -dataex- command to do so. If you are running version 17, 16 or a fully updated version 15.1 or 14.2, -dataex- is already part of your official Stata installation. If not, run -ssc install dataex- to get it. Either way, run -help dataex- to read the simple instructions for using it. -dataex- will save you time; it is easier and quicker than typing out tables. It includes complete information about aspects of the data that are often critical to answering your question but cannot be seen from tabular displays or screenshots. It also makes it possible for those who want to help you to create a faithful representation of your example to try out their code, which in turn makes it more likely that their answer will actually work in your data.

Thanks, Clyde. Also thanks for pointing out dataex. I'll be sure to use that in the future.
