XXXV. 180 (heading) A note on tests of significance in multivariate analysis. 1958Economist 29 Nov. 782 The multi-variate linear regression technique..is satisfactory only if the explanatory variables vary independently of each other or if the degree of interaction between two or more of them can be measured and allowed for. This is certainly not the case in milk production and it was for this reason that the technique was rejected. 1967C. Berners-Lee in Wills & Yearsley Handbk. Managem. Technol. i. 7 Procedures like multivariate regression analysis require a great deal of computation when more than a small number of variables are involved. 1968R. A. Bradley in Internat. Encycl. Social Sci. X. 527/1 Multivariate analysis in statistics is devoted to the summarization, representation, and interpretation of data when more than one characteristic of each sample unit is measured. 1972Computer Jrnl. XV. 215/2 Evaluation of the error matrix is therefore reduced to the evaluation of a multivariate polynomial at a number of points. 1973Nature 16 Mar. 210/3 Altogether, the theory of multi⁓variate distributions poses the most difficult problems in mathematical statistics. |
