k 组正态分布统计变量的独立性AI 解读

IN SUCH fields of investigation as economics, psychology, and anthropology, where observations on several variables are taken into account simultaneously, it is at least as important to study relationships among the variables as to consider the variables separately. In fact, if there are significant relationships within a system of variables, a considerable part of the information furnished by the observations will be lost unless the relationships are taken into account. In…

统计资料年度综述：国民支出的各组成部分AI 解读

THE econometric approach to statistics is a rather ambitious one. The econometrician is not content with mere description and historical or geographical comparison of economic data. He aims at obtaining invariant features of economic phenomena, invariant, at least, as long as the main institutional conditions of a given economic order do not substantially vary.

克努特·维克塞尔：计量经济学先驱AI 解读

THE progress of economic science from the Tableau e6conomique of Quesnay up to the Synthetic Economics of Moore may be symbolized by a tree gradually growing higher. The tree trunk is strongly rooted and its nature was determined by the place where it grew. Signs of a fresh orientation have become increasingly frequent during the last ten years, but, as yet, we do not see clearly which method to follow to unite the economics of yesterday to that of tomorrow. In the meantime,…
