By Jason Brownlee on August 12, 2019 in Machine Learning Algorithms 131 Share Post Share Linear regression is a very simple method but has proven to be very useful for a large number of situations. In this post, you will discover exactly how linear regression works step-by-step. After ...
Simple Linear Regression Now, for simple linear regression, we compute the slope as follows: To show how the correlation coefficient r factors in, let’s rewrite it as where the first term is equal to r, which we defined earlier; we can now see that we could use the “linear correlation...

Linear regression is a prediction method that is more than 200 years old. Simple linear regression is a great first machine learning algorithm to implement as it requires you to estimate properties from your training dataset, but is simple enough for beginners to understand. In this tutorial, you...
