• On the correlation of head measurements and mental agility - Women AI翻译
  作者：Musselman, JR
  作者单位：Johns Hopkins University
  摘要：After correction for age, head breadth, head length, and cephalic index of 1700 females are correlated with reaction time to sound and to sight. Correlation of head breadth and reaction time to sound, r = - .079 [plus or minus] .016. Other correlations are not significant. Means and standard deviations of head breadth and head length by age are given.
• Remains of Saint Magnus and Saint Rognvald, entombed in Saint Magnus Cathedral, Kirkwall, Orkney AI翻译
  作者：Reid, RW
  摘要：Description and measurements of skeletons.
• The corpuscle problem - Second memoir - Case of ellipsoidal corpuscles AI翻译
  作者：Wicksell, SD
  摘要：A mathematical paper in which the distribution of size of corpuscles in a tissue and total surface of corpuscles is derived from the distribution of size of contours of corpuscles in a section of the tissue.
• On the correlation of the mean and the variance in samples drawn from an infinite population AI翻译
  作者：Neyman, J
  摘要：The regression of the variance, [sigma]2, on the mean in samples from a population with any distribution is adequately represented by a 2nd order parabola. A method of testing whether a sample is likely to be from a population of known distribution is derived. One must be very cautious in drawing conclusions from Student''s test, if there be no good reason for supposing that the original frequency distribution is normal..
• A third study of the English skull with special reference to the Farringdon Street crania AI翻译
  作者：Hooke, BGE
  摘要：From the history of the site, the crania are of 17th century Londoners. Measurements were those taken by previous workers in Biometric Laboratory. Anomalies noted are discussed. The crania are similar to those of 17th century Londoners measured by Macdonell, all showing low retreating foreheads, and fairly similar to Lowland Scottish, but differ markedly from medieval Hythe and Rothwell crania. Regression formulae are given to estimate cranial capacity from the product of length, breadth, and ...
• A first study of the craniology of England and Scotland from Neolithic to early historic times, with special reference to the Anglo-Saxon skulls in London museums AI翻译
  作者：Morant, GM
  摘要：In late Neolithic times a homogeneous dolichocephalic race inhabited England and Scotland. The Bronze Age population included 3 elements: (1) a predominant brachy-cephalic type, (2) the Neolithic type, (3) hybrids between (1) and (2). The Iron Age population was homogeneous and intermediate. In England the late Celtic culture is not associated with a brachycephalic type. The Anglo-Saxon skulls show no evidence of differentiation into Angles, Saxons, and Jutes. They differ from the Iron Age typ...
• Further notes on non-linear regression AI翻译
  作者：Neyman, J
  摘要：General formulae are derived for the coefficients of an nth order parabolic regression line, and for the nth correlation ratio, Hn , connected with the nth parabola of regression as the correlation ratio n is connected with the actual regression line. The necessary and sufficient conditions for the actual regression line to be represented by an nth order parabola are also given.
