Level Up: Linear Regression in Python – Part 4

In the fourth lesson of the series, we’ll talk about the matrix representation of the linear regression problem. In the process, we’ll discuss the basics of matrix multiplication. We’ll also see how this mathematical understanding can prepare us to make sense of error messages that we might encounter when fitting a model in Python. Here…

Level Up: Linear Regression in Python – Part 3

In the third lesson of the series, we’ll implement our first linear regression model with multiple predictors (this is called “multiple linear regression”). As an example, we’ll use a simulated dataset to predict student quiz scores. In the process, we’ll again practice our graphing and Python skills. Here are some Stack Overflow questions related to…

Level Up: Linear Regression in Python – Part 2

In the second lesson of the series, we’ll learn how to fit and interpret a simple linear regression with a categorical predictor. We’ll use a simulated dataset to predict the amount of time someone will spend on a website based on the browser they are using. We’ll also predict the rental prices of NYC apartments…

Level Up: Linear Regression in Python – Part 1

Linear regression is a machine learning technique for modeling continuous outcomes. It is used for both prediction and data analysis in a variety of different fields. It is also the basis for a number of other machine learning models, including logistic regression and poisson regression. For anyone who is interested in learning more about data…
