The variability of characters within populations is generally measured as a function of the character variance, although questions of nongeographic variation are addressed as tests of mean differences ...

When a company plans a project, it will estimate the cost of the project before beginning. It may also estimate the amount of time it expects the project to take to complete. However, these estimates ...

Genetic interactions arise when the joint effect of alleles at two or more loci on a phenotype departs from simply adding up the effects of the alleles at each locus. Many examples of such ...

I have recently mentioned an analogy between the heritability of height & weight. That is, the proportion of variance of the trait which can be explained by variance in the genes. How closely do ...

This article proposes a new parameter, the group or class dominance probability, to measure the relative importance of random effects in one-way random effects models. This parameter is the ...

This article looks at a simple structured approach to assigning variance contributions and to assuring that the analytical procedure is fit for purpose. The ...

Variance is a statistical calculation that numerically describes the amount of variation in a data set. If values in a data set wildly fluctuate, variance would be high and predictions based on the ...
