Hi Everyone,

I write a new package called "rowsum" (my first package : ). It sums the values of multiple observations and saves results to a new observation.

For example, we have a dataset of population, GDP, ...... of many states, you can use "rowsum" to create a new observation of all southern states.

Please try
Code:
ssc install rowsum
and I provide two examples.

I welcome any suggestions and thank Kit Baum for all the help!

Best,
Pengzhan
