Question

Question 12 5 pts A linear regression model has been made, and the value of R2 for the model was 88.4%. The scatterplot of the data showed a strong linear pattern, but the residual plot for the model showed a random scatter of points with no real form. Based on these results, is this linear regression model likely to be a good model to use for making predictions? O No, there are issues with both the residual plot and the value of R? that raise doubts about the usefulness of this model's predictions. O Yes, there are no issues with anything reported here that raise doubts about the usefulness of our model's predictions. No, the residual plot having no form means that the predictions using this model are not as useful as they could be using another model. No, the form of the scatterplot and high value of R2 means that the predictions using this model are not likely to be useful.

Explanation / Answer

ANSWER:(b) Yes, there are no issues with anything reported here that raise doubts about the usefulnes of our model's prediction

After performing regression analysis we need to check the residual plots in order to validate our model.The non-random pattern in the residuals indicates that there might be some problem with the model, it may not be capturing some explanatory information that is “leaking” into the residuals. But while on the other hand residual plot with random scatter represents a better linkage of the model. While the value R2 square has no problem as such so we can
