Statistical computations and models for use with SciPy
Project description
What Statsmodels is
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: Generalized least squares (including weighted least squares and least squares with autoregressive errors), ordinary least squares.
glm: Generalized linear models with support for all of the one-parameter exponential family distributions.
discrete: regression with discrete dependent variables, including Logit, Probit, MNLogit, Poisson, based on maximum likelihood estimators
rlm: Robust linear models with support for several M-estimators.
tsa: models for time series analysis - univariate time series analysis: AR, ARIMA - vector autoregressive models, VAR and structural VAR - descriptive statistics and process models for time series analysis
nonparametric : (Univariate) kernel density estimators
datasets: Datasets to be distributed and used for examples and in testing.
stats: a wide range of statistical tests - diagnostics and specification tests - goodness-of-fit and normality tests - functions for multiple testing - various additional statistical tests
iolib - Tools for reading Stata .dta files into numpy arrays. - printing table output to ascii, latex, and html
miscellaneous models
sandbox: statsmodels contains a sandbox folder with code in various stages of developement and testing which is not considered “production ready”. This covers among others Mixed (repeated measures) Models, GARCH models, general method of moments (GMM) estimators, kernel regression, various extensions to scipy.stats.distributions, panel data models, generalized additive models and information theoretic measures.
