A teacher has created a simple linear regression model for a problem with two variables. The total variation in the model is partitioned as follows: SST = SSR+SSE = 780+ 320 What is the value of the coefficient of determination in this problem?
0.24 |
0.29 |
0.32 |
0.78 |
0.71 |
Yanıt Açıklaması:
Since the components of the total variation is already given then the coefficient of determination for this problem is as follows: r 2 = explained variation/ total variation = SSR / SST = = 780/ 780+ 320 = 0.71. Therefore, we can say that the 71% of the variability in the dependent variable can be accounted to the independent variable. The correct answer is E.
