statsmodels is a pure python package that provides classes and functions for the estimation of several categories of statistical models with numpy and scipy.
These currently include linear regression models, OLS, GLS, WLS and GLS with AR(p) errors, generalized linear models for six distribution
... [More] families and M-estimators for robust linear models, discrete models, Logit, Probit, Multinomial Logit, Poisson and Negative Binomial, models for time series analysis include AR, ARIMA and VAR. An extensive list of result statistics are available for each estimation problem. Besides models for estimation and prediction, statsmodels also has hypothesis tests and other statistical functions.

PyMacLab is the Python Macroeconomics Laboratory which serves the purpose of providing a convenience framework written in form of a Python library with the ability to solve non-linear DSGE models. The library supports solving DSGE models using 1st and 2nd order perturbation methods which are
... [More] computed around the steady state. PyMacLab possesses the added advantage of being equipped with an advanced model file parser module, which automates cumbersome and error-prone linearization by hand. PyMacLab is written entirely in Python, is free and incredibly flexible to use and extend. [Less]
