• On the use and interpretation of certain test criteria for purposes of statistical inference. Part II AI翻译
  作者：Neyman, J; Pearson, ES
  摘要：R. A. Fisher''s concept of likelihood is extended in this paper by defining the likelihood of the simple hypothesis that a sample, [SIGMA], has been drawn from a population, II, as [lambda] = C/C ([OMEGA]max.), where C is the chance of obtaining [SIGMA] from II, and C([OMEGA]max.) is the maximum chance of obtaining 2 from any population in the set [OMEGA]. The likelihood of the composite hypothesis that [SIGMA] has been drawn from one or the populations of the sub-set [omega] is defined as [la...
• A preliminary classification of European races based on cranial measurements. AI翻译
  作者：Morant, GM
  摘要：Based on the coefficient of racial likeness, a division into 5 groups is suggested: (A) Serbo-Croats, Turks, Greeks, Magyars, Slovenes, Roumanians, Czechs, Great Russians, Italians (Siena), with short skulls and large height-length index; (B) Swiss, Alsatians, Badensians, Wurtenberger, Bavarians (Altbayerisch and Waischenfeld), Vorarlberger, Tyrolese, English Bronze Age, with broad skulls and large breadth-height index; (C) Etruscans, Pompeians, Basques, Guanche, French, Copts; (D) English (Wh...
• A biometric study of one hundred and ten asiatic mandibles. AI翻译
  作者：Harrower, G
  摘要：Tamil, Hylam, Morant''s Tibetan A, and Hokien mandibles are closely alike, even when the crania differ.
• Similarities and differences in the species of the mulberry silk-worm AI翻译
  作者：Anoochin, AV
  摘要：Pearson''s coef-ficient of racial likeness is applied to silk-worm varie-ties.
• Note on standardisation of method of using the Coefficient of Racial LIkeness. AI翻译
  作者：Pearson, K
  摘要：Highly correlated characters and those with large errors of measurement should be avoided. A coefficient <3 probably does not mark a real racial difference. A correction for size of population is proposed.
• On the means of samples from a U-Shaped population AI翻译
  作者：Holzinger, KJ; Church, AER
  摘要：For samples <50 the distribution of means is composite in form and can not be represented satisfactorily by a simple continuous curve. In using Tippett''s random sampling numbers it is best to allocate the numbers anew for each set of samples. When a distribution of means is representable by a Pearson curve, the goodness of fit depends more on the grouping than on the number of samples taken.

  摘要：Tamil, Hylam, Morant''s Tibetan A, and Hokien mandibles are closely alike, even when the crania differ.
• On the importance of the type silhouette for racial characterisation in anthropology. AI翻译
  作者：McLearn, I; Morant, GM; Pearson, K
  摘要：The technique of making type silhouettes is described. The English [female] and negro [male] silhouettes resemble each other except in the mouth and chin.
• Frequency distribution of an index when both the components follow the normal law AI翻译
  作者：Merrill, AS
  摘要：For conditions ordinarily met with, the frequency distribu-tion of the index, when both components follow the normal law closely, is sensibly normal. In other cases, particularly where the correlation is high and the coefficients of variation are large, there may be a considerable deviation from normality.
• On the use and interpretation of certain test criteria for purposes of statistical inference Part I AI翻译
  作者：Neyman, J; Pearson, ES
  摘要：The problem: Given a sample 2 and a hypothesis A that it has been drawn at random from a population n[long dash]how shall the hypothesis be tested? The 1st attempt to solve this problem resulted in Bayes'' Theorem. However, the application of that theorem requires knowledge of the a priori probability law, which follows directly from the problem under consideration only in exceptional cases. All that can be done is to assume some definite form of the a priori law, for instance, that it is cons...
