This package provides a Python module and a Bash interface which can compute the probability of a 2-choice popular election being decided by one vote. Predictions are based on either a series of forecasts, a beta (or normal) probability density function for outcomes, or a fixed outcome probability.
Input:
pyvote one 2000000 -f 0.519 0.55 0.492 0.53 0.515
Output:
The probability of a single vote deciding an election with 2000000 voters and forecasts of 0.519, 0.55, 0.492, 0.53, and 0.515 in favor of the preferred choice is 1.12534199273483e-5.
As the population is even, this probability is the sum of the probabilities of turning a tie into a victory (5.62662750202373e-6) and turning a loss into a tie (5.62679242532457e-6).
Depending on your preferred package manager you may choose one of the following methods:
PyVote is available via Portage (the package manager of Gentoo Linux, derivative distributions, and installable on any other Linux distribution, or BSD) via the Chymeric Overlay. Upon enabling the overlay, the package can be emerged:
emerge pyvote
Alternatively, the live (i.e. latest) version of the package can be installed along with all of its dependencies without the need to enable to overlay:
git clone git@github.com:TheChymera/pyvote.git
cd pyvote/.gentoo
./install.sh
Python's setuptools allows you to install Python packages independently of your distribution (or operating system, even).
This approach is (by design) not particularly powerful in managing dependencies;
as such, given any other alternative, we do not recommend this approach:
git clone git@github.com:TheChymera/pyvote.git
cd pyvote
python setup.py install --user
Python's setuptools allows you to install Python packages independently of your distribution (or operating system, even);
it also allows you to install a "live" version of the package - dynamically linking back to the source code.
This permits you to test code (with real module functionality) as you develop it.
This method is sub-par for dependency management (see above notice), but - as a developer - you should be able to manually ensure that your package manager provides the needed packages.
git clone git@github.com:TheChymera/pyvote.git
cd pyvote
echo "export PATH=\$HOME/.local/bin/:\$PATH" >> ~/.bashrc
source ~/.bashrc
python setup.py develop --user
If you are getting a Permission denied (publickey) error upon trying to clone, you can either:
- Add an SSH key to your GitHub account.
- Pull via the HTTPS link
git clone https://github.com/IBT-FMI/SAMRI.git.
The most precise specification of the dependency graph can be extracted from the pyvote ebuild. For manual dependency management and overview you may use the following list:
