3. Sum Of Squares Due To Regression 通过以上我们能得到以下关于他们三者的关系 4、 决定系数: 判断 回归方程 的拟合程度 (coefficient of determination)决定系数也就是说: 通过回归方程得出的 dependent variable 有 number% 能被 independent variable 所解释. 判断拟合的程度 单独看 R-Squared,并不能推断出增...
增加一个特征变量,如果这个特征有意义,Adjusted R-Square 就会增大,若这个特征是冗余特征,Adjusted R-Squared 就会减小。 (Correlation coefficient) 相关系数 : 测试dependent variable 和 independent variable 他们之间的线性关系有多强. 也就是说, independent variable 产生变化时 dependent variable 的变化有多大. 可...

Unlike the coefficient of determination, the coefficient of correlation: A. indicates the percentage of variation explained by a regression model. B. measures the strength of association between the two variables more exactly. C. indicates whether the slope of the regression line is positive or nega...

performing basic math functions, such as multiplication and linear graphing, the TI-84 Plus can find solutions for problems in algebra, calculus, physics and geometry. It can also calculate statistics functions, including finding the correlation coefficient and coefficient of determination of a data ...
