I'm working through a dummy multi-regression example and I think I'm good with the calculations part.
I'm confused on the Revenue (Y) Prediction part. Can I change the both variables at the same time to make the Revenue prediction? Or do I need to hold one independent variable as...
Can someone help me add 95% confidence intervals to the Predicted Y below. I understand calculation of Predicted Y but I'm not sure how to calculate the confidence bands around each value of Predicted Y.
Any help would be greatly appreciated.
