population correlation coefficientsimple linear regressionOne of the simplest and yet a commonly occurring data analytic problem is exploring the relationship between two numerical variables. In many applications, one of the variables may be regarded as a response variable and the other as a predictor ...
Linear Correlation Coefficient 线性相关系数(又称为“皮尔逊相关系数”)通常用字母r表示,用以衡量两个变量的线性相关程度。 它有以下特点: r的取值总是在−1到+1之间; 取值越远离 0 , 说明两者的线性相关性越强; 正负号表明两者是正相关(y 随着 x 增大而增大)还是负相关 (y 随着 x 增大而减少)。
直线相关与回归Linearcorrelationandr egression 直线相关与回归 前面介绍的统计方法都只涉及单一变量，即或进行两组或多组比较，所比较的仍然是同一变量，而且是以讨论各组间该变量的相差是否显著为中心环节。医学领域里常可在一个统一体中遇到两个或多个变量之间存在着相互联系、相互制约的情况.如:同一批水样的浊度与...
