'CONFIDENCE INTERVALS'

HOTELLING, HAROLD.

The Generalization of Student's Ratio.

Ann Arbor, Edwards Brothers, 1931. 8vo. In the original grey printed wrappers. Offprint from: "The Annals of Mathematical Statistics", August, 1931. Very light miscolouring to wrappers, otherwise a very fine copy. Pp. 360-378.

Scarce offprint of Hotelling's landmark paper on what was later termed as 'Confidence Intervals'.

"Important as was his contribution to economics, most of his effort and his influence were felt in the field of mathematical statistics, particularly in the development of multivariate analysis. In a fundamental paper [the present], he generalized Student's test to the simultaneously test of hypotheses about the means of many variables with a joint normal distribution. In the course of this paper, he gave a correct statement of what were later termed 'confidence intervals'. (The New Palgrave).
