Ordinary Least Squares:
a. Maximizes R^2
b. Maximizes SSR
c. Estimates the regression line with the minimum variance
d. Minimizes SSE
e. All of the above
Solution:
Ordinary Least Squares:
a. Maximizes R^2
b. Maximizes SSR
c. Estimates the regression line with the minimum variance
d. Minimizes SSE
e. All of the above
Answer: e. All the above
Because all the above are mostly used in the ordinary least squares method of regression hence answer is all the above
Thank You..!!

What would be the value of the sum of squares due to regression (SSR) if the total sum of squares (SST) is 25.32 and the sum of squares due to error (SSE) is 6.89? a. 31.89 b. 19.32 c. 18.43 d. 15.32
1. In regression analysis, the Sum of Squares Total (SST) is a. The total variation of the dependent variable b. The total variation of the independent variable c. The variation of the dependent variable that is explained by the regression line d. The variation of the dependent variable that is unexplained by the regression line Question 2 In regression analysis, the Sum of Squares Regression (SSR) is A. The total variation of the dependent variable B. The total variation of the independent variable...
