2 1 Getting Started Statsmodels Api V1 Github Pages

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. We download the Guerry dataset, a collection of historical data used in support of Andre-Michel Guerry’s 1833 Essay on the Moral Statistics of France. The data set is hosted online in comma-separated values format (CSV) by the Rdatasets repository. We could download the file locally and then load it using read_csv, but pandas takes care of all of this automatically for us: statsmodels is a Python package that provides a complement to scipy for statistical computations including descriptive statistics and estimation and inference for statistical models.

The documentation for the latest release is at The documentation for the development version is at Recent improvements are highlighted in the release notes https://www.statsmodels.org/stable/release/ This page provides a series of examples, tutorials and recipes to help you get started with statsmodels. Each of the examples shown here is made available as an IPython Notebook and as a plain python script on the statsmodels github repository.

We also encourage users to submit their own examples, tutorials or cool statsmodels trick to the Examples wiki page State space modeling: Local Linear Trends Fixed / constrained parameters in state space models TVP-VAR, MCMC, and sparse simulation smoothing From bottom of this page: http://statsmodels.sourceforge.net/stable/index.html statsmodels is a Python module that provides classes and functions for the estimation of many different statistical models, as well as for conducting statistical tests, and statistical data exploration.

An extensive list of result statistics are available for each estimator. The results are tested against existing statistical packages to ensure that they are correct. The package is released under the open source Modified BSD (3-clause) license. The online documentation is hosted at statsmodels.org. statsmodels supports specifying models using R-style formulas and pandas DataFrames. Here is a simple example using ordinary least squares:

You can also use numpy arrays instead of formulas: Have a look at dir(results) to see available results. Attributes are described in results.__doc__ and results methods have their own docstrings.

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.

The package is released under the open source Modified BSD (3-clause) license. The online documentation is hosted at statsmodels.org. Since version 0.5.0 of statsmodels, you can use R-style formulas together with pandas data frames to fit your models.
