[No place, no printer], 1927. 8vo. Without wrappers (as issued). Offprint from: ""Journal of the American Statistical Association"", September, 1927. Fine and clean. Pp. 283-314.
Scarce offprint of Hotelling's paper on differential equations in statistics. ""Harold Hotelling, a creative thinker in both mathematical statistics and economics. [...] His influence on the development of economic theory was deep though it occupied a relatively small part of a highly productive scientific life devoted primarily to mathematical statistics"" only ten of some 87 published papers were devoted to economics, but of these sic are landmarks which continue to this to lead to further developments"" (New Palgrave).
[Various places and printers], 1927 - 1953. Collection of 4 offprint from various academic journals. All with wrappers (or as issued) and in fine condition.
Collection of offprints by mathematical statistician and economic theorist Harold Hotelling. He is famous for Hotelling's T-squared distribution and its use in statistical hypothesis testing and confidence regions. He also introduced canonical correlation analysis and has a crucial place in the growth of mathematical economics.
[No place, no printer], 1931. 8vo. Without wrappers (as issued). Offprint from: ""Journal of the American Statistical Association"", June, 1931. Fine and clean. Pp. 135-149.
Scarce offprint of Hotelling's important paper on in which it for the first time is statistically demonstrated that a delayed dip in birthrates will occur with populations iwhen subjected to harvest failures or epidemics.
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).
