open source computational probability software
Project description
A Probability Progamming Language (APPL) – Python Edition
ABOUT:
ApplPy is a computational probability package written in Python. The project runs using the open source SymPy computer algebra system (CAS). Because all of the dependencies that ApplPy requires to run are open source, ApplPy is available free of charge. While still incomplete, ApplPy will eventually be capable of performing a wide range of random variable algebra operations on univariate probaility distributions. The package supports both continuous and discrete distributions, as well as piece-wise distributions. The current capabilities of ApplPy include:
Conversion between PDF,CDF,SF,HF,CHF and IDF representations of random variables
Computation of expected values, with both numeric and symbolic output
Plotting distributions, including piece-wise distributions
One-to-one and many-to-one transformations of piecewise distributions
Convolutions of lifetime distributions
Random sampling from distributions
Bootstrapping data sets
ApplPy is derived from A Probability Programming Language (APPL), which runs in Maple. The idea behind ApplPy is to make the capabilites of APPL available on a free of charge, open source platform. This has the potential to make APPL much more effective, both as an educational resource and a research tool.
INSTALLATION:
ApplPy requires the following dependencies in order to run properly:
SymPy
Matplotlib
The latests stable release of both of these packages can be downloading from the python package index at https://pypi.python.org/pypi
The latest working edition of APPLPy is available on GitHub and the latest stable release is available from the python package index. To install the software, open the directory where APPLPy has been downloaded and type the following command
$ python setup.py install
If you have any comments or suggestions for ApplPy, feel free to contact the author at mthw.wm.robinson@gmail.com. Users with Python experience are encouraged to get in touch and contribute.
