Hello; I need help answering these questions step by step in excel and interpreting the data using three and four variables. Thank you in advance :)
Find the best multiple linear regression (based on R2) using two independent variables. Observe Multiple R, R-squared, Significant F, P-values and interpret. Observe the residuals and standard residuals of the model. Use the following guidelines to assign performance rating on scale of 1-7. If the standard residuals is:
-3.00 and lower Rating of 1
-3.00 to -2.00 Rating of 2
-2.00 to -1.00 Rating of 3
-1.00 to +1.00 Rating of 4
+1.00 to +2.00 Rating of 5
+2.00 to +3.00 Rating of 6
+3.00 and higher Rating of 7
Find the best multiple linear regression using three independent variables. Observe Multiple R, R-squared, Significant F, P-values and interpret. Observe the residuals and standard residuals of the model. Assign ratings based on table above.
