Article Link: http://dx.doi.org/10.1093/biomet/76.4.803 AbstractA semiparametric estimator of natural mortality, introduced by Hearn, Sandland & Hampton (1987), was studied by Leigh (1988), who noted that its asymptotic variance may sometimes be infinite. We discuss the nonnorrnal asymptotic behaviour that can occur in this case, and remark on difficulties that it causes in practice. Barndorff-Nielsen, O.E., James, I.R., Leigh, G.M.
