Linear Regression Algorithm In Python From Scratch [Machine Learning Tutorial]

We'll build a linear regression model from scratch, including the theory and math. Linear regression is the most popular machine learning algorithm, and implementing it in python will help you understand how it works. First, we'll cover the theory and the equation to calculate the coefficients. Then we'll implement the equation in python. We'll end by calculating the r squared value to figure out how well our regression fits the data. We'll be using data from the Olympics to implement our algorithm. We'll try to predict how many medals a country will earn based on how many athletes it enters into the Olympics. You can find the code and data at https://github.com/dataquestio/projec... .
