- Statsmodels is a Python package that provides a complement to scipy for statistical computations including descriptive statistics and estimation and inference for statistical models.
- Main Features
- Linear regression models:
- Mixed Linear Model with mixed effects and variance components
- GLM: Generalized linear models with support for all of the one-parameter exponential family distributions
- GEE: Generalized Estimating Equations for one-way clustered or longitudinal data
- Discrete models:
- Logit and Probit
- Multinomial logit (MNLogit)
- Poisson regression
- Negative Binomial regression
- RLM: Robust linear models with support for several M-estimators.
- Time Series Analysis: models for time series analysis
- Complete StateSpace modeling framework
- Seasonal ARIMA and ARIMAX models
- VARMA and VARMAX models
- Dynamic Factor models
- Markov switching models (MSAR), also known as Hidden Markov Models (HMM)
- Univariate time series analysis: AR, ARIMA
- Vector autoregressive models, VAR and structural VAR
- Hypothesis tests for time series: unit root, cointegration and others
- Descriptive statistics and process models for time series analysis
- Survival analysis:
- Proportional hazards regression (Cox models)

- QUOTE: Statsmodels is a Python module that allows users to explore data, estimate statistical models, and perform statistical tests. An extensive list of descriptive statistics, statistical tests, plotting functions, and result statistics are available for different types of data and each estimator. Researchers across fields may find that statsmodels fully meets their needs for statistical computing and data analysis in Python. Features include:
- Linear regression models.
- Generalized linear models.
- Discrete choice models.
- Robust linear models.
- Many models and functions for time series analysis
- Nonparametric estimators.
- A collection of datasets for examples
- A wide range of ..statistical test]]s.
- Input-output tools for producing tables in a number of formats (Text, LaTex, HTML) and for reading Stata files into NumPy and Pandas.
- Plotting functions.
- Extensive unit tests to ensure correctness of results
- Statsmodels runs on Python 2.6 through 3.4.
