Abstract
We consider Buckley-James estimation in simple linear regression applied to the Stanford heart transplant data. We describe an experiment in which the ages of patients are perturbed. The number of limiting values of Buckley-James estimates exhibits chaotic behaviour. By considering the ordering of the residuals we obtain formulae for the limiting values of the regression coefficients.
