偏相关分析是指当两个变量同时与第三个变量相关时,将第三个变量的影响剔除,只分析另外两个变量之间相关程度的过程,判定指标是相关系数的R值。 p值是针对原假设H0:假设两变量无线性相关而言的。一般假设检验的显著性水平为0.05,你只需要拿p值和0.05进行比较:如果p值小于0.05,就拒绝原假设H0,说明两变量有线性相关的关系,他们无线性相关的可能性小于0.05;如果大于0.05,则一般认为无线性相关关系,至于相关的程度则要看相关系数R值,R越大,说明越相关。越小,则相关程度越低。
Further verifications is carried out by factor analysis and the value of significance for each category is tested. To eliminate the interference among the variables, partial correlation analysis is conducted to modify the original result.
