Dear statalist,
I'm trying to calculate a "locational Gini coefficient" (rg) by using the formula in a reference paper in the following:
rg=(sum|x_i-x_j|)/(2*n^2*u)
where n is the total number of industries in an area, i and j are just two industries in n industries, x is the market share of any industry, and u is the mean of x.
I have not idea how to put x_i-x_j into stata.
Thanks and best regards,
Amy
