TABLE 3.

Mean and standard deviation (in parentheses) of r² for a sample of size 25 (10⁴ iterations) under the “multiple-mergers” process (η = 0) and the mixture-distribution process (η = 1)

In each case φ = 1. The predicted values are ϒ(ω) for the multiple-mergers process and ϒ₂(1, 1, ω) for the mixture-distribution process (see Table 2).

^aLow-frequency (<10%) variants excluded.
