How to use alorenz to test the second order stochastic dominance?

[Zoraze Ali]

Hi

I am a very new user to STATA and trying to look for a way to test second order stochastic dominance. I found alorenz package which have this functionality but i am unable to understand the format of input to this method. My query is as follows,

Q1. In which format should I arrange my data, e.g, Simple two columns, one for group and second for the values?


I would be very thankful if someone could give an example for the usage of this method. I am attaching here an example of the format of my data for your reference.

Kind regards,
