integrating scikit learn and statsmodels for regression

Statistics and Machine Learning both aim to extract insights from data, though their approaches differ significantly. Traditional statistics primarily concerns itself with inference, using the entire dataset to test hypotheses and estimate probabilities about a larger population. In contrast, machine learning emphasizes prediction and decision-making, typically employing a train-test split methodology where models learn from a portion of the data (the training set) and validate their predictions on unseen data (the... In this post, we will demonstrate how a seemingly straightforward technique like linear regression can be viewed through these two lenses. We will explore their unique contributions by using Scikit-Learn for machine learning and Statsmodels for statistical inference. Kick-start your project with my book Next-Level Data Science.

Find the correlation between each of the numerical columns to the house price

Whether you’re a beginner exploring your first regression model or an experienced data scientist shipping production models, chances are you’ve run into two core Python libraries: statsmodels and scikit-learn. They both let you fit models, analyze data, and generate predictions, but they’re built for very different goals. This is why, in this tutorial, we’ll break down: Think of statsmodels as your statistical lab coat. It’s designed for exploratory data analysis, hypothesis testing, and interpreting relationships between variables. If you’ve used R before, you’ll find statsmodels refreshingly familiar.

On the other hand, scikit-learn is built for machine learning at scale. Mastering multiple linear regression with Python, scikit-learn, and statsmodels is a crucial skill for data scientists looking to build predictive models. This article guides you through implementing MLR, from preprocessing data to evaluating model performance using techniques like cross-validation and feature selection. You’ll learn how to use powerful tools like scikit-learn and statsmodels to predict outcomes such as house prices based on key factors, including median income and room size. By the end, you’ll understand how to measure the model’s effectiveness with metrics like R-squared and Mean Squared Error. Multiple Linear Regression is a statistical method used to predict an outcome based on several different factors.

It helps to understand how different independent variables, like house size, number of bedrooms, and location, can influence a dependent variable, such as the price of a house. This method is applied by creating a mathematical model that explains the relationship between these variables and can be used to predict future values. Multiple Linear Regression (MLR) is a pretty basic statistical method, and it’s super helpful for modeling how one thing (the dependent variable) relates to two or more other things (the independent variables). It’s kind of like an upgrade to simple linear regression, which only looks at the relationship between one dependent variable and one independent variable. But with MLR, you’re diving deeper to see how multiple factors work together to influence the thing you’re trying to predict. You can use it to predict future outcomes based on these relationships.

So, here’s the thing: multiple linear regression works on the idea that there’s a straight-line relationship between the dependent variable and the independent variables. What that means is, as the independent variables change, the dependent variable will change in a proportional way. Let’s look at an example to make it clearer: imagine you’re trying to predict how much a house costs. Here, the price of the house would be the dependent variable ?, and your independent variables ?₁, ?₂, ?₃ might be things like the size of the house, the number of bedrooms, and where... In this case, you can use multiple linear regression to figure out how these factors (size, bedrooms, location) all come together to affect the price of the house.

StatsModels is a Python library that specializes in statistical and time-series analyses. StatsModels and Scikit-Learn communities have co-existed since early 2010s. Yet, there is virtually no co-operation between the two, even though the potential for synergy is high. In essence, StatsModels provides low-level tools for formulating and testing statistical hypotheses, whereas Scikit-Learn provides a high-level framework for organizing those tools into coherent and transparent workflows.

StatsModels’ linear models and Scikit-Learn’s linear models are compatible in their fit and predict behaviour, but address different application scenarios: The biggest differentiator is model introspection capabilities.
