respectively.
- Compute R2 (to 3 decimals).
- Compute Ra2 (to 3
decimals).
- How good is the fit provided by the estimated regression
equation?
SelectThe estimated regression equation provided an excellent fitThe estimated regression equation provided a moderately good fitThe estimated regression equation did not provide a good fit
Homework Answers
Answer #1
The values are R2 & R2adj are near to 1 .so this is an excellent fit.almost all variation in the dependent variable is explained by regression model.
