Oftentimes, in biomedical engineering research or design, we are interested in whether there is a correlation between two variables, populations, or processes. These correlations may give us information about the underlying biological processes in normal and pathologic states and ultimately help us to ...
Simple Linear Regression and CorrelationCopyright © 2005 Brooks/Cole, a division of Thomson Learning, Inc.17.1Linear Regression Analysis… Regression analysis is used to predict the value of one variable (the dependent variable) on the basis of other variables (the independent variables). Dependent...

In many applications, one of the variables may be regarded as a response ...
Linear Correlation Coefficient 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)。 一般来说,如果 |r| 的值大于0.85,说明两者线性强相关;取值在0.5至0.85,为中等程度相关;取值在0.1...
Linearcorrelationandregression 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透光率,同一批人的...
