A Beginner's Guide to Machine Learning Regression Analysis

Examples, diagrams, animations, and cheat sheets are used to illustrate regression analysis.

CONTEXT-

Consider the following basic example to gain a better understanding of the inspiration behind regression. From 2001 to 2012, the scatter plot below displays the number of college graduates in the United States.

What if someone asked you, based on the available data, how many college graduates with master's degrees will there be in 2018? The number of college graduates with master's degrees increases almost linearly with the passing of each year. So, based on a quick visual review, we can estimate the number to be between 2.0 and 2.1 million. Let's take a peek at the numbers. From 2001 to 2018, the same variable is plotted in the graph below. As can be shown, our expected value was within a few percent of the actual value.
