Stats can seem like a lot—formulas, weird names like p-values, confidence intervals—it’s easy to feel lost. But what if I told you there’s a Python library that makes all of this way easier to work with?

Thank god too, because I am not great with a lot of the math and stats that goes on behind the scenes so that’s where statsmodels comes in.

This library doesn’t get talked about as much as it should, but it’s seriously useful. It helps you run all kinds of statistical tests, build models, and actually understand what your data is saying.

Welcome to statsmodels. Check out other 3 Random Articles here.

Imagine you're subscribed to a newsletter called 3 Randoms. Each week, it introduces you to three lesser-known Python tools that can make your coding better. It's like expanding your toolbox and discovering new tricks.

Whether you’re just running a simple linear regression or working with time series data, statsmodels gives you the tools and explanations to make sense of it all.

To be honest, when I first opened it up, I felt overwhelmed. The documentation felt like reading a textbook, and the output looked like a wall of numbers. But once I stuck with it and started using it on real projects, things started to click.

In this article, I’m going to show you how to use statsmodels to build solid statistical models, understand the results, and even check whether your assumptions hold up. If you’ve ever wanted to analyze trends, compare different groups, or just feel more confident talking about data—this is for you.

Oh, and to answer your first question, “Does this replace Scikit-Learn?” The answer is no, this is geared towards statistical modeling and inference. It gives you detailed summaries, p-values, confidence intervals, and other stats that help you understand why a model is behaving that way.

It’s not the flashiest library out there, but once you get the hang of it, you’ll wonder how you managed without it.

Let’s dive in. First, go ahead and run this in your terminal:

pip3 install statsmodels

👉 Thank you for allowing me to continue to do work that I find meaningful. This is my full time job so I hope you will support my work.

My premium readers get access to so much more, like monthly Python projects, in-depth weekly articles, this here '3 Randoms' series, and my complete archive!

👉 If you get value from my work, please leave it a ❤️ and share it. This helps more people discover this newsletter, which helps me out immensely!

Now let’s roll up our sleeves and actually get into what your data’s been trying to tell you from the get-go.
