The Analysis of Two‐Way Tables with Missing Values
SUMMARY A method is given for calculating missing values in a two-way table that conforms to a row linear model. Verification of conformance to the model and analysis of the data are explained with an example of real data.

The Distribution of Eigenvalues of Covariance Matrices of Residuals in Analysis of Variance
A rigorous definition is given for the concept of an interaction matrix (Z* lij*s) where i=1 to m and j=1 to n, in terms of two idempotent matrices A*lr*s and B*ls*s of rank r and s, respectively. It is then shown that the frequency distribution of the eigenvalues of (Z)(Z)' depends only on r and s. Applications are given to matrices of residuals arising from two-way data, either by removing row and/or column-means, or by applying any number of sweeps of the vacuum cleaner. The theorems are important in the theory of the analysis of two-way tables of nonadditive data.
