This very simple case-study is designed to get you up-and-running quickly with statsmodels. Starting from raw data, we will show the steps needed to estimate a statistical model and to draw a diagnostic plot. We will only use functions provided by statsmodels or its pandas and patsy dependencies. After installing statsmodels and its dependencies, we load a few modules and functions:

pandas builds on numpy arrays to provide rich data structures and data analysis tools. The pandas.DataFrame function provides labelled arrays of (potentially heterogenous) data, similar to the R “data.frame”. The pandas.read_csv function can be used to convert a comma-separated values file to a DataFrame object. patsy is a Python library for describing statistical models and building Design Matrices using R-like formulas. This example uses the API interface. See Import Paths and Structure for information on the difference between importing the API interfaces (statsmodels.api and statsmodels.tsa.api) and directly importing from the module that defines the model.

We can then read any of those formats back as a pd.DataFrame: import statsmodels.api as sm model = sm.OLS (y,x) results = model.fit () results_summary = results.summary () # Note that tables is a... The table at index 1 is the “core” table. The model is estimated using ordinary least squares regression (OLS). To fit most of the models covered by statsmodels, you will need to create two design matrices. The first is a matrix of endogenous variable (s) (i.e. dependent, response, regressand, etc.).

The answer from @Michael B works well, but requires “recreating” the table. The table itself is actually directly available from the summary ().tables attribute. Each table in this attribute (which is a list of tables) is a SimpleTable, which has methods for outputting different formats. What do you need to know about Statsmodels in Python? Statsmodels is a Python module which provides various functions for estimating different statistical models and performing statistical tests First, we define the set of dependent ( y) and independent ( X) variables. If the dependent variable is in non-numeric form, it is first converted to numeric using dummies.

When dealing with data analysis and statistical modeling in Python, two powerful libraries often shine: pandas and statsmodels. Pandas, with its robust data manipulation capabilities, can handle large datasets efficiently, while statsmodels offers statistical tests and data exploration capabilities. The combination of these two libraries can significantly enhance your data manipulation skills and expand your analytical toolset. Before we dive into integration tactics, it is crucial to understand the individual functionalities of both libraries. First, ensure you have both libraries installed in your environment: Let's quickly load the libraries in Python:

Pandas can read and write diverse data formats like CSV, Excel, SQL databases, and more. For example, to read data from a CSV file: Now, you have a DataFrame named data that you can manipulate, summarize, and transform. Pandas, an incredibly versatile data manipulation library for Python, has various capabilities to calculate summary statistics on datasets. Summary statistics can give you a fast and comprehensive overview of the most important features of a dataset. In the following article, we will explore five methods of computing summary statistics using Pandas.

The describe() method is a strong method to generate descriptive statistics of a DataFrame. The describe() method will provide you with detailed summary statistics including count, mean, standard deviation, min, 25th percentile, median (50th percentile), 75th percentile, and max. Explanation: In this, we create a dictionary with numerical values and convert it to a Pandas Dataframe. We then used the describe() function on the DataFrame which provides a summary of key statistics including count, mean, standard deviation and percentiles. Pandas also has distinct functions to calculate the mean, median and mode of each column in a DataFrame. Explanation: mean() function calculates the average of each column, median() finds the middle value when sorted and mode() identifies the most frequent value.

Since mode() returns a DataFrame, we extract the first row using .iloc[0]. Last modified: Jan 23, 2025 By Alexander Williams The summary() function in Python's Statsmodels library is a powerful tool for statistical analysis. It provides a detailed overview of model results. This guide will help you understand how to use it effectively. The summary() method is used to generate a comprehensive report of a statistical model.

It includes coefficients, standard errors, p-values, and more. This is essential for interpreting model performance. To use summary(), you first need to fit a model. For example, let's fit a linear regression model using Statsmodels. This code fits a simple linear regression model and prints the summary. The output includes key statistics like R-squared, coefficients, and p-values.
