Table 2. Tradeoff between bias and precision in the estimation of λ.

c	Bias (%)	Standard error (%)
22	3.1	0.6
23	2.6	0.7
24	2.1	0.8
25	1.7	0.9
26	1.4	1.0

36	0.0	4.0
37	0.0	4.5

The bias in the estimation of λ is calculated from Table 1, assuming λ’s true value is 0.2670. The standard error assumes an experiment generating 1/10 000 the number of island scores shown in Table 1.
