For the data set: Hospital Complete of Chapter 5

Work out the details of the Stepwiseregression, and Backward model selection for the data set Hospital Complete from chapter 5.

I would like you to not use SAS option "stepwise" or "backward" in the code, but rather go through the steps of the algorithmsyourselves. In other words, run as many regression models as needed.

Indicate the variables you include in/exclude from the model, on what basis, and the final model you have arrived at.
