title: FACTOR ANALYTICAL TREATMENT OF GROWTH DATA.
abstract: This paper presents a limited linear factor analysis model for the analysis of repeated measures of several traits on the same subjects. Attention is drawn to the problem of analysing growth in mean scores, and an analytical resolution of this problem, together with an appropriate method of analysis, is presented for the case of independent error terms. A special condition, expected to hold for some data, is discussed, and the corresponding rotational procedures derived. Data from an artificial experiment satisfying the model are analysed to illustrate the methods evolved.
