In order to evaluate the statistical properties of the variance components method implemented in SOLAR and GENEHUNTER2, the type I error rate, power and estimated ...

The Annals of Mathematical Statistics, Vol. 27, No. 3 (Sep., 1956), pp. 737-748 (12 pages) The sampling variance of the least squares estimates of the components of variance in an unbalanced ...

The authors explore likelihood-based methods for making inferences about the components of variance in a general normal mixed linear model. In particular, they use local asymptotic approximations to ...

We first describe the likelihood of the commonly used variance components model, for example as in Amos. 5 Since the total likelihood is a product of likelihood over all the families under study, we ...

Learn what analysis of variance (ANOVA) is, how it works, and when to use it. See how it helps compare means across multiple data groups in statistics and research.

Now perform a variance components analysis on the original data. Press the button in the Measurements window and select Variance Components. The results are displayed, as shown in Display A.15.

Mean, the overall average of the dependent variable. This gives an unbiased estimate of the mean of the population. Its variance is estimated by a certain linear combination of the estimated variance ...

Jim Manzi has a long post up on epistasis, that is, gene-gene interactions: We could call this process of competing algorithms struggling to find the best solution as fast as possible "meta-evolution" ...
