"WebThe estimates of variance components are the unbiased ANOVA estimates. They are obtained by setting each calculated mean square equal to its expected mean square, which gives a system of linear equations in the unknown variance components that is then solved. Unfortunately, this approach can cause negative estimates, which should be set to zero. " - In the anova

WebThe adjusted sums of squares can be less than, equal to, or greater than the sequential sums of squares. Suppose you fit a model with terms A, B, C, and A*B. Let SS (A,B,C, A*B) be the sum of squares when A, B, C, and A*B are in the model. Let SS (A, B, C) be the sum of squares when A, B, and C are included in the model. Analysis of variance (ANOVA) is a collection of statistical models and their associated estimation procedures (such as the "variation" among and between groups) used to analyze the differences among means. ANOVA was developed by the statistician Ronald Fisher. ANOVA is based on the law of total variance, where the observed variance in a particular variable is partitioned into components attributable to different sources of variation.
