经济计量学诞生于20世纪初,是一门新的实证经济科学。对经济计量学模型结构参数估计目前常用的方法有最小二乘法和最大似然法。随着社会的发展变化,最小二乘法的不足之处日益突出,系列假设前提也显得更为不科学。为此各国计量经济学家早已从事计量经济学新方法的研究和探索。曹定爱同志著的《累积法引论》便是诸多研究和探索中最先出现的闪光点之一。该书的特点有: (1)方法的独创性。累积法是一种曲线拟合技术,其基本思想是利用有关数据的累积和及权数直接估计模型有关参数。所谓累积和就是对某列数据按照一定的叠加规律进行不同叠加后所得到的结果。累积法的雏形是由意大利数学家马尔奇西首创,累积法的计算过程极为
Econometrics was born in the early 20th century, is a new empirical economics. The most commonly used methods to estimate the structural parameters of econometric models are the least square method and the maximum likelihood method. With the development of society, the deficiencies of the least-squares method have become increasingly prominent. The series of assumptions also appear to be more unscientific. For this purpose, econometricians of various countries have long been engaged in the research and exploration of new methods of econometrics. Comrade CAO Dingai’s Citation Methodology is one of the first flash points in many studies and explorations. The book features are: (1) the originality of the method. Cumulative method is a curve fitting technique, the basic idea is to use the cumulative and weight of the relevant data to directly estimate the parameters of the model. The so-called cumulative and is a column of data in accordance with a certain law of superposition of different superposition of the results obtained. The rudiment of Cumulative Law was invented by the Italian mathematician Malchise. The calculation of Cumulative Law is extremely
