Create a Linear Regression model in Python
Using the data below for bill and tips
Use the 2 stubbed out python files as a starting point
Manually build out a Linear Regression model in Excel (2 points) （这个两分的我自己做掉）
Show calculation for EACH step in the excel
Basically you are manually creating a model that calculates every step individually
Use the Python starting scripts provided below (3 points)
hw9.py (this is specific to what we are using it for - bills and tips)
This is complete, except you need to change
the value for line 8 and
the name of your module
marc_module.py (this is generic and does not mention bills or tips because we can using it for ANYTHING)
Rename this file to match your name(Yixuan) or ID(yh3791)
Create functions for each of the excel calculations and place between line 12 to 15
Hint: You will need other global variables outside of the functions to help with the other steps (place these variables after line 5)
Call each function from the above step in logical order, in calculate()
Change predict to return a prediction for what ever value passed in
