PPT-Contrasts in ANOVA Decomposition of Treatment Sums of Squares using prior information

1 Contrasts notation For a Oneway ANOVA a contrast is a specific comparison of Treatment group means Contrast constants are composed to test a specific hypothesis related to Treatment means based upon some prior information about the Treatment groups For k treatment groups contrast constants are a sequence of numbers .

When designs are “unbalanced”, typically with missing values, our estimates of Treatment Effects can be biased.. When designs are “unbalanced”, the usual computation formulas for Sums of Squares can give misleading results, since some of the variability in the data can be explained by two or more variables..
