交易流总体分析的统计模型AI 解读

This is applicable to the flow of any kind of quantifiable transactions, and to matrices from three to more than one hundred actors, utilizing a 650 IBM electronic computer or similar equipment. The method develops a matrix of expected or baseline data from assumptions of complete indifference among the actors, and measures the plus or minus differences between this baseline value and the actual amount of transactions in each direction for every pair of actors. It thus…

二元序列的回归分析AI 解读

Summary A sequence of 0’s and 1’s is observed and it is suspected that the chance that a particular trial is a 1 depends on the value of one or more independent variables. Tests and estimates for such situations are considered, dealing first with problems in which the independent variable is preassigned and then with independent variables that are functions of the sequence. There is a considerable amount of earlier work, which is reviewed.

效用树的经验含义AI 解读

The hypothesis considered is that the utility function can be written as U U[VA (qai , * **, qX**, VM(q?1 , , q.,)], where the V's are utility functions depending on quantities of different commodities assigned to different branches (e.g., food, clothing). This hypothesis implies certain empirically meaningful and interesting conditions on the price coefficients of the demand functions. These conditions are, however, not subjected here to statistical test. A price index…

适用于截断数据的两类位置变化检验比较AI 解读

Summary The powers of one and two-sample tests of change of centre of location based on the difference of sample quantiles are compared with those of the corresponding combinatorial tests based on quantile division of the sample. The powers are found to be asymptotically equivalent. Computation of particular cases suggests that for quite small samples there is good agreement of the powers of the two kinds of test with each other and with their common limiting form.

不完全重复的成对比较设计分析AI 解读

Experiments involving paired comparisons have mainly concerned the situation where each judge compares all possible pairs of treatments or objects. In certain types of experiments, this may require an excessive number of comparisons to be made by any observer. To overcome this handicap, Bose (1956) and Kendall (1955) constructed certain designs, symmetrical with respect to objects and judges, which do not require each judge to compare all possible pairs of objects. However,…

伽马分布较低分位点非参数寿命检验的渐近效率AI 解读

This paper does not present new statistical methods. Rather, it shows that a well known nonparametric procedure which is valid under extremely general conditions also has high efficiency and other favorable properties for certain types of life testing situations. This nonparametric method is the sign test and its confidence interval and point estimate analogs. Sign test procedures and methods of applying them have already received extensive coverage in the literature (e.g.,…
