However, Statview's F-test procedure yielded unequal variances for several metabolite concentrations and metabolite ratios, and common tests for normal distribution do not give meaningful results when applied to small sample groups [51], [52].
Third, we used a quantitative genetics experiment to estimate the phenotypic means and variances for several key life-history traits of offspring produced by crossing Coccibelle® with the French invasive population.
We detected significant genetic dominance and/or shared sibling environment variance components for several traits.
Using analysis of variance (ANOVA) for several means, we set the statistical power to 0.80 based on estimates of sample variation and effect size obtained in our pilot experiments.
The estimates from the method of Zuk et al. are significantly lower than those using IBD-segment based variance components for several of the traits (glucose is the one exception).
We calculate variance error bars for several published sets of measurements of mtDNA mutation level variance and show how the addition of the error bars alters the interpretation of these experimental results.
Figure 1 Bias, variance, and RMS for several CoD estimators versus actual CoD under a Zipf model with, for and varying number of bins.
Figure 2 Bias, variance, and RMS for several CoD estimators versus number of bins (b = 4, 8, 12, and 16) under a Zipf model with, for actual CoD = 0.6 and varying sample size.
Figure 4 Bias, variance, and RMS for several CoD estimators versus sample size (n = 20, 30, 40, 50, and 60) under a Zipf model with, for actual CoD = 0.6 and varying number of bins.
