Two Methods of Computing Matrices of Within-Group Correlations Using Full Model Dummy Variables.
Peer reviewed Peer reviewed
Coles, Gary J. – Multiple Linear Regression Viewpoints, 1979
This paper discusses how full model dummy variables can be used with partial correlation or multiple regression procedures to compute matrices of pooled within-group correlations. (Author/CTM)

Full Rank and Non-full Rank Models with Contrast and BJ Binary Coding Systems for Two-Way Disproportionate Cell Frequency Analyses
Peer reviewed Peer reviewed
Williams, John D. – Multiple Linear Regression Viewpoints, 1977
The problems of two way analysis of variance designs with unequal and disproportionate cell sizes are discussed. A variety of solutions are discussed and a new solution is presented. (JKS)
