classes and functions for the estimation of statistical models

 scikits.statsmodels is a pure Python package that provides classes
 and functions for the estimation of several categories of statistical
 models. These currently include linear regression models, OLS, GLS,
 WLS and GLS with AR(p) errors, generalized linear models for six
 distribution families and M-estimators for robust linear models. An
 extensive list of result statistics are available for each estimation
 problem.
