Name: quantecon | ||
Version: 0.1.7-2 | ||
Summary: QuantEcon is a package to support all forms of quantitative economic modelling. | ||
Home-page: https://github.com/QuantEcon/QuantEcon.py | ||
Author: Thomas J. Sargent and John Stachurski (Project coordinators) | ||
Author-email: john.stachurski@gmail.com | ||

Description: | ||
**QuantEcon** is an organization run by economists for economists with the aim of coordinating | ||
distributed development of high quality open source code for all forms of quantitative economic modelling. | ||
|
||
The project website is located at `http://quantecon.org/ <http://quantecon.org/>`_. This website provides | ||
more information with regards to the **quantecon** library, documentation, in addition to some resources | ||
in regards to how you can use and/or contribute to the package. | ||
|
||
The **quantecon** Package | ||
------------------------- | ||
|
||
The `repository <https://github.com/QuantEcon/QuantEcon.py>`_ includes the Python package ``quantecon`` | ||
|
||
Assuming you have `pip <https://pypi.python.org/pypi/pip>`_ on your computer --- as will be the case if you've `installed Anaconda <http://quant-econ.net/getting_started.html#installing-anaconda>`_ --- you can install the latest stable release of ``quantecon`` by typing | ||
|
||
pip install quantecon | ||
|
||
at a terminal prompt | ||
|
||
Repository | ||
---------- | ||
|
||
The main repository is hosted on Github `QuantEcon.py <https://github.com/QuantEcon/QuantEcon.py>`_ | ||
|
||
**Note:** There is also a Julia version available for Julia users `QuantEcon.jl <https://github.com/QuantEcon/QuantEcon.jl>`_ | ||
|
