Hi all,
I would like to ask if anyone can identify and/or tell me how to run a certain descriptive statistic in Stata. I am working with a nominal variable and would like to provide some indication of the variability within the sample along this variable. I would like to use a statistic discussed by Agresti in his categorical data analysis book that gives the probability that two randomly selected independent observations in a given dataset will end up in different categories of the given variable. The statistic has a minimum value of 0 and a maximum value of J-1. Can anyone tell me what this descriptive statistic is called? More importantly, can anyone tell me the order needed to run it in Stata? Thank you very much, Kevin.
