You’ll then learn how to fit simple linear regression models with numeric and categorical explanatory variables, and how to describe the relationship between the response and explanatory variables using model coefficients. Hi, my name is Maarten and welcome to the course.

You will be learning about regression, a statistical tool to analyze the relationships between variables. Let’s start with an example. This dataset on Swedish motor insurance claims is as simple as it gets. Each row represents a region in Sweden, and the two variables are the number of claims made in that region, and the total payment made by the insurance company for those claims, in Swedish... Predict housing prices and ad click-through rate by implementing, analyzing, and interpreting regression analysis with statsmodels in Python. This course focuses on utilizing Python statsmodels for linear and logistic regression, two widely used statistical models.

Linear regression analysis is a statistical technique for predicting the value of one variable(dependent variable) based on the value of another(independent variable).

The dependent variable is the variable that we want to predict or forecast. In simple linear regression, there's one independent variable used to predict a single dependent variable. In the case of multilinear regression, there's more than one independent variable. The independent variable is the one you're using to forecast the value of the other variable. The statsmodels.regression.linear_model.OLS method is used to perform linear regression. Linear equations are of the form:

Syntax: statsmodels.regression.linear_model.OLS(endog, exog=None, missing='none', hasconst=None, **kwargs) Return: Ordinary least squares are returned. Importing the required packages is the first step of modeling. The pandas, NumPy, and stats model packages are imported. Completing the course on Introduction to Regression with statsmodels in Python, I gained a comprehensive understanding of regression analysis and its application in Python. Here’s a summary of what I learned:

Fundamentals of Regression: I learned the basics of regression analysis, including the difference between linear and logistic regression models. Fitting Simple Linear Regression Models: I explored how to fit linear regression models with both numeric and categorical explanatory variables and how to interpret model coefficients to describe relationships between the response and explanatory... Making Predictions: I learned how to use linear regression models to make predictions on various datasets, providing actionable insights from the model’s outputs. Regression to the Mean: I gained an understanding of the concept of “regression to the mean” and its implications in statistical analysis. Simple linear regression is a basic statistical method to understand the relationship between two variables. One variable is dependent, and the other is independent.

Python’s statsmodels library makes linear regression easy to apply and understand. This article will show you how to perform simple linear regression using statsmodels. Simple Linear Regression is a statistical method that models the relationship between two variables. The general equation for a simple linear regression is: This equation represents a straight-line relationship. Changes in X lead to proportional changes in Y.

Simple linear regression helps to understand and measure this relationship. It is a fundamental technique in statistical modeling and machine learning. First, install statsmodels if you haven’t already: We will use a simple dataset where we analyze the relationship between advertising spending (X) and sales revenue (Y). The goal is to gain the skills you need to fit simple linear and logistic regressions. Exploring the relationships between variables in real-world datasets, including motor insurance claims, Taiwan house prices, fish sizes, and more.

Linear regression and logistic regression are two of the most widely used statistical models. You’ve probably seen data where a simple straight line just doesn’t cut it. Maybe you’re modeling bike rentals and temperature, where the relationship looks more like a mountain than a slope. Or perhaps you’re analyzing medical data where effects taper off at extreme values. This is where Generalized Additive Models come in. Statsmodels provides GAM functionality that handles penalized estimation of smooth terms in generalized linear models, letting you model complex patterns without losing interpretability.

Think of GAMs as the middle ground between rigid linear models and black-box machine learning. Linear regression assumes your features have a straight-line relationship with your outcome. Real data laughs at this assumption. Between 0 and 25 degrees Celsius, temperature might have a linear effect on bike rentals, but at higher temperatures the effect levels off or even reverses. GAMs replace each linear term in your regression equation with a smooth function. Instead of forcing a straight line, they fit flexible curves that adapt to your data’s natural shape.

The key difference from something like polynomial regression is that GAMs use splines, which are piecewise polynomials that connect smoothly at specific points called knots. Here’s what makes this useful. You can capture common nonlinear patterns that classic linear models miss, including hockey stick curves where you see sharp changes, or mountain-shaped curves that peak and decline. And unlike random forests or neural networks, you can still explain what your model is doing.
