Added code and answered questions for assignment 2

What did you learn from the changes you have made?

I learnt more about Linear Regression, Multiple Regression and evaluation method such as RMSPE. To evaluate further I rewatch the lecture videos and learnt a bit more about r2. I also plan to experiment further. I might make further updates based on findings.

Was there another approach you were thinking about making? If so, what approach(es) were you thinking of?

I am new to Linear Regression so I was mostly rewatching the videos and learning/

Were there any challenges? If so, what issue(s) did you face? How did you overcome it?

There were challenges but I rewatched the videos and did some experimental coding. I plan to do some more studying.

How were these changes tested?

I mostly tested them by looking at the graphs, and try RMSPE and r2.
