举一反三
- Pearson’s product moment correlation coefficient 可用来判断：
- In regression analysis, if the coefficient of determination is 1.0, then the coefficient of correlation must be 1.0.
- The Pearson coefficient of correlation r equals 1 when there is/are no:
- If the coefficient of correlation r = 0, then there is no linear relationship whatsoever between the dependent variable y and the independent variable x.
- Even if the correlation coefficient is high (near +1) or low (near-1), it may not be significant. True or false? A: 正确 B: 错误
