Multiple Linear Regression
You can have more than one input variable. This raises a tough question - what should be in the model, and what shouldn’t be? Remember, the R^2 value will always go up with more data.
The coefficient intervals for a predictor might not even overlap between regressions of different sets of inputs.
| P> | t | - lower means more significant |
