Fitting one matrix to another under choice of a central dilation and a rigid motion

- P. Schönemann, R. Carroll
- Mathematics
- 1 June 1970

A least squares method is presented for fitting a given matrixA to another given matrixB under choice of an unknown rotation, an unknown translation, and an unknown central dilation. The procedure… Expand

Alpha Coefficients for Stratified-Parallel Tests

- L. Cronbach, P. Schönemann, D. Mckie
- Psychology
- 1 July 1965

IN an internal-consistency study investigators almost always rely on the KR20 formula or its generalized version «, a coefficient most appropriate for tests formed by random sampling of items… Expand

On models and muddles of heritability

- P. Schönemann
- Biology
- Genetica
- 2005

One reason for the astonishing persistence of the IQ myth in the face of overwhelming prior and posterior odds against it may be the unbroken chain of excessive heritability claims for… Expand

The minimum average correlation between equivalent sets of uncorrelated factors

- P. Schönemann
- Mathematics
- 1 March 1971

A simplified proof of a lemma by Ledermann [1938], which lies at the core of the factor indeterminacy issue, is presented. It leads to a representation of an orthogonal matrixT, relating equivalent… Expand

A maximum likelihood solution for the method of successive intervals allowing for unequal stimulus dispersions

- P. Schönemann, L. Tucker
- Mathematics
- 1 December 1967

A maximum likelihood solution for the method of successive intervals is presented together with an iterative procedure for obtaining estimates for stimulus scale values, boundary scale values, and… Expand

Saliency metric for subadditive dissimilarity judgments of rectangles

- A. Lazarte, P. Schönemann
- Psychology, Medicine
- Perception & psychophysics
- 1 March 1991

Previous findings that dissimilarity judgments for rectangles are strongly subadditive, that qualitative individual differences are always present, and that four-parameter psychophysical maps can… Expand

A solution to the weighted procrustes problem in which the transformation is in agreement with the loss function

- R. W. Lissitz, P. Schönemann, J. Lingoes
- Mathematics
- 1 December 1976

This paper provides a generalization of the Procrustes problem in which the errors are weighted from the right, or the left, or both. The solution is achieved by having the orthogonality constraint… Expand

Some new results on factor indeterminacy

- P. Schönemann, Ming-mei Wang
- Mathematics
- 1 March 1972

Some relations between maximum likelihood factor analysis and factor indeterminacy are discussed. Bounds are derived for the minimum average correlation between equivalent sets of correlated factors… Expand
