In regression analysis, if the coefficient of determination is 1.0, then the coefficient of correlation must be 1.0.
举一反三
- If the coefficient of determination is 0.975, then the slope of the regression line:
- 2(marks 3). Which of the following is an incorrect statement. A: The product moment correlation coefficient can be used with non-numeric data. B: The product moment correlation coefficient is the definitive measure of correlation. C: The rank correlation coefficient can be used as an approximation to the product moment coefficient. D: The rank correlation coefficient can be used with non-numeric data .
- If the value of the sum of squares for error, SSE, equals zero, then the coefficient of determination must equal zero.
- The Pearson coefficient of correlation r equals 1 when there is/are no:
- Pearson’s product moment correlation coefficient 可用来判断：
