-- IF YOU DON'T HAVE ACCESS TO AN APPLICATION THAT CAN RUN JUPYTER NOTEBOOKS YOU WILL NEED TO INSTALL ONE...  Here are directions for how to start.

1.) Installation instructions (if needed)

-- Install anaconda from www.anaconda.com downloads page

-- Download anaconda installer for your operating system (e.g., MAC or...?)

-- Run the installer... it takes a couple minutes.

-- Open the Anaconda-Navigator 

-- Open a Jupyter notebook, you're ready to rock.

2.) Open "LeastSquaresRegression.ipynb" as a Jupyter notebook, and begin running it cell by cell.  You can do that by, e.g., simply clicking the first cell and then hitting SHIFT+RETURN.  You need to execute the cells in order or things will not work as intended...

3.) Read along and enjoy form cell to cell...  In the meantime you can pick up some python basics...
