Normal linear models with genetically structured residualvariance heterogeneity : a case study. Residual by observed values were plotted to examine the assumption that residualvariance was randomly distributed. This measure describes how much of the residualvariance was eliminated from the baseline model. They do not arise because of any difference between genotypes in their environmental or residualvariance. The mean value of the residualvariance before selection is given by exp(b+s2/2). Further, the residualvariance estimates were grossly overestimated. For the normal data, a flat but bound prior was chosen for the residualvariance. But, it does increase the residualvariance which, in turn, can affect hypothesis testing. Both of these findings are indications that the residualvariance is systematic. The indices were logtransformed and weighted with the reciprocal of the residualvariance for each comparison. We assume residualvariance to be homogeneous across families for both methods. Because, despite this systematic effect, the squared bias for the variable model is lower than that for the fixed model, the residualvariance around the regression must also be lower. We fit four models with different levels of complexity in the residualvariance structure, with the simplest being the standard repeatability homogeneous variance additive genetic model. The first is to investigate the presence of additive genetic effects influencing the log residual variance and their possible correlation with the genetic effects influencing the expected litter sizes. Heritability estimates are given by the ration of the additive genetic variance to the sum of the between-family variance and the residualvariance. This assumption simplifies the mathematical manipulation of the residualvariance-covariance matrix (inversion, factorization, etc.), but may deviate from reality. There is, moreover, strong evidence of a negative correlation between the additive genetic values affecting litter size and those affecting residualvariance. The main effect of using cofactors is the reduction in the residualvariance leading to a higher test statistic. These examples are from corpora and from sources on the web.
