The chapter explains how to formulate research problems where correlation matrix and partial correlation can be used to draw conclusions; the procedure of using SPSS in computing correlation matrix and partial correlation; and interpret the output of SPSS....
偏相关(Partial Correlation)是用于测量两组变量之间的直接线性关系,而排除了其他变量的影响。与通常的相关性(Correlation)不同,偏相关不仅仅衡量两组变量间的关联性,还能够排除第三个(或多个)控制变量的干扰,反映两个变量之间的净相关性。 换句话说,偏相关可以理解为在固定其他变量不变的情况下,两个变量之间的线性...

partial correlation偏相关(Partial Correlation)用于衡量两个变量在排除其他变量影响后的直接线性关系,其核心在于消除混杂因素的干扰。该系数取值范围为[-1, 1],绝对值越大表示净相关性越强。以下是具体解析: 1. 概念与意义 偏相关通过控制其他变量(如Z)的影响,计算两个目标变量(如X...
The meaning of PARTIAL CORRELATION is the correlation between two statistical variables under the condition that all other relevant variables are fixed.

partial explanation───部分解释 partial fraction───[数]部分分式;[数]部分分数 双语使用场景 Objective To analyze the partial correlation problems by multilevel bivariate models.───目的探讨利用双变量多水平模型分析多重相关中的部分相关问题。 Conclusion Multilevel bivariate models are effective methods...
Partial correlation has one continuousindependent variable(the x-value) and one continuousdependent variable(the y-value); This is the same as in regular correlation analysis. In the blood pressure example above, the independent variable is “amount of food eaten” and the dependent variable is “...
