Lorenz curves and Gini coefficients. Before we get to startup funding and its inequality — which, of course, is more feature than bug — let’s understand our curves and coefficients.

This paper extends the recent methodology of Beach and Davidson, 1983, on performing statistical inference with Lorenz curves and quantile shares to samples which involve weighted observations.
