In (4.17) a factor W is missing in the numerator of the expression in the middle. 2. The predictor of Xorns proposed in Paragraph 5B is not unbiased in general as a simple counterexample will show. The proposed reserve on an individual orns claim with past history T, U, V > υ′ = τ - T - U, {Y′(υ″); 0 ≤ υ″ ≤ υ′}, is Suppose that Y = V and Y′(υ″) = Q(υ″/V)V, 0 ≤ υ″ ≤ V, where Q is a non-decreasing, deterministic function on [0,1] such that Q(0) = 0 and Q(1) = 1. In this case R = E[V∣T, U, V > Y′(υ′)] - Y′(υ′). If Q(s) > s for all s ∈ (0, 1), then Y′(υ′) = Q(υ′/V)V > υ′, hence Copyright © International Actuarial Association 1999 ASTIN Bulletin Cambridge University Press 29/1(1999-05), 27-27 0515-0361 29:1<27 1999 29 ASB https://doi.org/10.2143/AST.29.1.504604 text/html Onlinezugriff via DOI 1 research-article jats NATIONALLICENCE 856 40 https://doi.org/10.2143/AST.29.1.504604 text/html Onlinezugriff via DOI NATIONALLICENCE 100 1- Norberg Ragnar NATIONALLICENCE 773 0- ASTIN Bulletin Cambridge University Press 29/1(1999-05), 27-27 0515-0361 29:1<27 1999 29 ASB CC0 http://creativecommons.org/publicdomain/zero/1.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-cambridge
