Abstract:

10.1093/biomet/93.2.411

Arising from an omitted term in a calculation in the Appendix, variance formulae in the paper should be adjusted. In particular, the constants in the numerators of equations (2·4) and (2·15) should be 6 rather than 18. Variances are, however, still higher than in the case of least-squares estimators. The changes are implied by the following corrections to the Appendix. On p. 423, 2cδΔ′<inf>cos</inf>(ω^(k)) should be included within braces on lines 11 and 17, and 2cδΔ′<inf>sin</inf>(ω^(k)) should be added within braces on lines 12 and 18, leading to the extra term 2cm^−3/2{Δ′<inf>sin</inf>(ω^(k))γ<inf>sin</inf>^(k) + Δ′<inf>cos</inf>(ω^(k))γ<inf>cos</inf>^(k)} on line 21. We are grateful to Barry Quinn for drawing our attention to this error.
