The rank-size (size measured in values in millions of dollars) relationship:
. reg lnrank lnvalue,r

Regression with robust standard errors Number of obs = 100
F( 1, 98) = 534.79
Prob > F = 0.0000
R-squared = 0.9545
Root MSE = .19892

( 1) lnvalue = -1

F( 1, 98) = 10.40
Prob > F = 0.0017


Here's a graph of the actual and fitted values from the simple Zipf-type regression:



I am continually amazed at how often such rank-size relationships prevail in the world.
