| Abstract: | Regression approach to one-way (one-factor) Analysis of Variance problems was investigated using indicator variables to represent the selection of data from alternative levels (treatments) of the factor. A matrix, U of indicator variables Xi j was obtained, from which 1 () tt U U U y yielded the means of the output responses 1corresponding to given treatments rightoff- the-bat. The key benefit is that the matrices and , ( ) , t t t U U U U U y
1 () tt U U U y have very simple structures, which could be deployed for an easy generation of a desired ANOVA table and the establishing of Confidence and Prediction intervals. |
