Denominator Synthesis

A method developed by Satterthwaite (1946) which finds the linear combinations of sources of random variation that serve as appropriate error terms for testing the significance of the respective effect of interest in mixed-model ANOVA/ANCOVA designs.

For descriptions of denominator synthesis, see the Introductory Overview for the Variance Components and Mixed-Model ANOVA/ANCOVA method of analysis and the Introductory Overview for the General Linear Model (GLM) method of analysis.
