A piecewise method for estimating the Lorenz curve

We propose a piecewise method to estimate the Lorenz curve for grouped income data. Our illustrative application shows that the method can produce more plausible density when the income distribution data has multiple peaks and the Lorenz curve cannot be modeled satisfactorily over the entire interval with a single Lorenz curve model.
