Analysis of Variance (ANOVA) is a statistical method used to analyze the differences among group means in a sample. It is particularly useful for comparing three or more groups for statistical significance. In Python, the statsmodels library provides robust tools for performing ANOVA. This article will guide you through obtaining an ANOVA table using statsmodels, covering both one-way and two-way ANOVA, as well as repeated measures ANOVA.

ANOVA is a powerful statistical method used to determine if there are any statistically significant differences between the means of two or more independent groups. It is widely used in various fields, including medicine, social sciences, and engineering. ANOVA can be one-way, two-way, or even multi-way, depending on the number of factors being analyzed. The key components of an ANOVA table include: One-way ANOVA is used when you have one independent variable and one dependent variable. Here's how to perform one-way ANOVA using statsmodels.

Step-by-Step Guide for evaluating one-way anova with statsmodels: 2. Fit the Model and Obtain the ANOVA Table: Two-way ANOVA is used when you have two independent variables. It helps in understanding if there is an interaction between the two factors on the dependent variable. Step-by-Step Guide for evaluating two-way anova with statsmodels:

Analysis of variance (ANOVA) compares the means across two or more groups to test the null hypothesis that all group means are equal. It breaks down the total variance in the data into two components: variance between groups and variance within groups. There are several types of ANOVA, predominantly including: In Python, the statsmodels library makes ANOVA easy to perform. It supports both one-way and two-way ANOVA. This article demonstrates how to use statsmodels for ANOVA with simple examples.

You’ll learn how to prepare data, fit models, and interpret the results. Before getting started, make sure you have the required libraries installed: Now, you can import the necessary modules: Analysis of Variance models containing anova_lm for ANOVA analysis with a linear OLSModel, and AnovaRM for repeated measures ANOVA, within ANOVA for balanced data. A more detailed example for anova_lm can be found here: Anova table for one or more fitted linear models.

AnovaRM(data, depvar, subject[, within, ...]) Repeated measures Anova using least squares regression This page documents the components and functionality of the Results and Summary Tables system in statsmodels, which provides tools for formatting, displaying, and exporting model results in various formats. For information about creating data structures and specifying models, see Data Handling and Model Formula Interface. The results and summary system enables users to generate publication-quality output from statistical model results in text, HTML, LaTeX, and CSV formats, facilitating model interpretation across different environments (console, Jupyter notebooks, academic papers). The key components of the results and summary tables system are:
