Porter presents an excellent account of the young Karl Pearson and his extraordinarily varied activities. These ranged from the Cambridge Mathematical Tripos Exams to German history and folklore, and included free thought, socialism, the woman's question, and the law. Returning to science, Pearson produced the famous Grammar of Science . He decided on a career in statistics only at age 35. Porter emphasizes Pearson's often acrimonious but largely successful battles to show the wide applicability and importance of statistics in many areas of science and public affairs. Eugenics became a passion for Pearson. Avoiding all formulas Porter fails to give any concrete ideas of even Pearson's most important contributions to statistical theory. We try to sketch these here. 相似文献

This paper considers the language devised by Karl Pearson and his associates for discussing distributions, populations and samples, the basic language for frequentist inference. The original language—some of which is still in use—is described and also the changes it underwent under the influence of R.A. Fisher and of Russian and American mathematicians. The period covered is roughly 1890–1950. 相似文献

In the paper we study regressional versions of Lukacs' characterization of the gamma law. We consider constancy of regression
instead of Lukacs' independence condition in three new schemes. Up to now the constancy of regressions of U=X/(X + Y) given V=X + Y for independent X and Y has been considered in the literature. Here we are concerned with constancy of regressions for X and Y while independence of U and V is assumed instead. 相似文献
