In the results, craniometric traits section (page 325), the significance test for the unbiased, estimated genetic D2 value was incorrectly stated as using a Z-distribution test method. A t-ratio test method was actually utilized.

Craniometric Traits

The cranial metric analysis focuses on the same three island populations used in the analysis of cranial non-metric traits. The averaged unbiased, estimated genetic D2 values and standard errors are presented in Table 4. The values clearly indicate that the Nuku Hiva sample was nearly equally divergent from the Fatuiva and Tahuata/Hiva 'Oa samples, while the Fatuiva and Tahuata/Hiva ';Oa samples were relatively close to each other. These results support those obtained by cranial discrete trait analyses. Each unbiased, estimated genetic D2 value was tested to determine if the value was significant using Z-distribution test method in which the distance value is divided by its standard error. The unbiased, estimated genetic D2 values for the Nuku Hiva-Fatuiva (0.1328, 46-variable analysis; 0.2726, seven-variable analysis) and the Nuku Hiva-Tahuata/Hiva 'Oa (0.0813, 46-variable analysis; 0.2225, seven-variable analysis) pairings were stastically significant, while the Fatuiva-Tahuata/Hiva 'Oa (0.0433; 0.0427) pairings were not statistically significantly different from zero, using the Z-distribution test method.

Table 4 & 5 Footnotes:

2 Significant estimated genetic D2 value: Z(0.05, 7) = 2.365

3 Significant estimated genetic D2 value: Z(0.05, 46) = 2.015

Each unbiased, estimated genetic D2 value was tested to determine if the value was significant using t-ratio test method (distance value divided by its standard error) and Student's t degrees of freedom (Schafer, 1999). The unbiased, estimated genetic D2 values for the Nuku Hiva-Fatuiva (0.1328, 46-variable analysis; 0.2726, seven-variable analysis) and the Nuku Hiva-Tahuata/Hiva 'Oa (0.0813, 46-variable analysis; 0.2225, seven-variable analysis) pairings were stastically significant, while the Fatuiva-Tahuata/Hiva 'Oa (0.0433; 0.0427) pairings were not statistically significantly different from zero, using the t-ratio test method.
