Question

20世纪以前数理统计学发展的一个重要成果，是19世纪后期由英国遗传学家兼统计学家高尔顿发起，并经现代统计学的奠基人之一K·皮尔逊和其他一些英国学者所发展的统计相关与回归理论。所谓统计相关，是指一种非决定性的关系如人的身高X与体重Y，存在一种大致的关系，表现在X大（小）时，Y也倾向于大（小），但非决定性的：由X并不能决定Y。现实生活中和各种科技领域中，这种例子很多，如受教育年限与收入的关系，经济发展水平与人口增长速度的关系等，都是属于这种性质，统计相关的理论把这种关系的程度加以量化，而统计回归则是把有统计相关的变量，如上文的身高X和体重Y的关系的形式作近似的估计，称为回归方程，现实世界中的现象往往涉及众多变量，它们之间有错综复杂的关系，且许多属于非决定性质，相关回归理论的发明，提供了一种通过实际观察去对这种关系进行定量研究的工具，有着重大的认识和实用意义。

Answer 1

Before the 20th century,the most important achievement in the field of mathematical statistics were statistical correlation and regression theory,which was presented by Galton----the geneticist and statist from United Kingdom during the late period of 19th century.Besides Galton,one of the founders of modern statistics Pearson and other researchers from UK also participated in the development of mathematical statistics. Statisticla correlation means that there is a kind of link within inconclusive relationship, such as the height X and weight Y,specifically manifested in when X becomes large(small),Y also becomes larger(small).However,Y cannot be decided by the value of X.In the real life and the area of science and technology,there are various of examples like this,which involves the relationship between the years of being educated and income;the development of economics and the increasing rate of population,they all belong to this nature.The theory about statistic makes such relationship quantized,and statistical regression call the variable quantity which relate to statistic as regression equation,like which was said before,the relationship between height X and weight Y.The phenomenon in the ture world always relate to various of variable quantity,there are many complicated relationships between them and the majority of them belong to non deciding properties.The discovery of regression theory provides the way to understand this by observation,thus it has significant meaning for human beings.

20 century ago mathematical statistics the development of an important achievement, is in the late nineteenth century by the British geneticists and statisticians gore's launch, and one of the founders of the modern statistics k. Pearson and some other British scholar in the development of statistical correlation and regression theory. The so-called statistical correlation, it is to point to a kind of the decisive relations such as height and weight Y X, the existence of a roughly, the relation between the performance in the X (small), Y also tend to high (low), but the decisive: by the X and Y can't decide. The real life and all kinds of science and technology field, this example many, such as education and income by the relationship between the fixed number of year, economic development level and the relationship between the velocity of population growth, it is to belong to the nature, statistics related theory, the relationship between the degree of quantization, and statistics regression is put a statistical related variables, such as the above height and weight of the X Y of the relationship between the approximate form of the estimate, called the regression equation, the phenomenon of the real world often in many variables, are they of the complicated relationship, and many belong to the nature of the decision, the invention of the correlated regression theory, and provides a through the actual observation to the relationship between the quantitative tools, has a major knowledge and practical significance.
