摘要:

By the ‘image’ of a variable is meant the multiple regression of that variable on all the other variables in the data to be analysed, and its ‘anti‐image’ the error of estimate. It is then shown that an expression forR, the ordinary matrix of covariances or correlations, can be obtained in terms of the covariance matrices of the images and anti‐images respectively. Various theorems and identities are deduced which lead to new structural theories forRand for data in the social sciences generally. In particular fresh light is thrown on the problems of parsimo

摘要:

A procedure is explained for the construction of preference tables which set out in a systematic scheme the results obtained by using the method of ranks, paired comparison, or some other type of multiple comparison; and the detailed properties of such tables are described. Such a table may be used to exhibit the dispersion of objects in a multi‐dimensional space of individuals' preferences or the dispersion of individuals in a space of preferences for objects; and the two devices are shown to be complementary. Methods of analysing and studying tables of this kind are discussed and illustrate

摘要:

The purpose of the following article is to explain a technique for describing and comparing bivariate patterns in which a number of subjects respond to a number of items. A new scoring procedure is proposed for the responses based on a simple weighting principle, which leads to a convenient formula for comparing two or more patterns. The advantages of the method are discussed; and it is suggested that it may have useful applications in other fields.

摘要:

An approach to the study of the covariance structure and the discriminating properties of psychological tests is proposed for cases in which the tests can be classified hierarchically and suitably scaled. The method makes use of a Model II analysis of variance, with certain modifications, and provides statistical tests which are not available for the more general methods of factor analysis.

摘要:

When the scores obtained with the WISC battery of tests from children attending a psychiatric clinic were compared with those obtained from normal children, they showed a greater dispersion. Attempts to explain the discrepancy in terms of selection, non‐normality, or emotional and environmental factors, proved unconvincing. An application of Bartlett's formulae for the sampling theory of ability suggested that the difference might be due to genetic factors arising from pronounced assortative matin
