摘要
在相关分析中 ,通常利用相关系数来分析或测定这些变量之间的线性相关程度 ,然而 ,简单相关系数受其他因素的影响 ,反映的往往是非本质的联系。要准确地反映两个经济变量之间的内在联系 ,需要计算偏相关系数。通过偏相关系数与相关系数的比较 ,来确定这两个变量之间的内在线性联系会更真实 ,更可靠。
In the related analysis, the correlation coefficient is generally used to analyze and determine the linear's related degrees of variables. Because it is affected by other factors, what the simple correlation coefficient reflects is not the essence of relations. In order to reflect exactly the internal relations between the two economic variables, it needs calculating the biased correlation coefficient. By comparison with biased correlation coefficient and correlation coefficient, it will be more real and reliable to determine the internal linear relations between the two variables.
