This is the code repository for Bayesian Analysis with Python, published by Packt. It contains all the supporting project files necessary to work through the book from start to finish.
All of the code is organized into folders. Each folder starts with a number followed by the application name. For example, Chapter02.
The code will look like the following:
n_params = [1, 2, 4]
p_params = [0.25, 0.5, 0.75]
x = np.arange(0, max(n_params)+1)
f, ax = plt.subplots(len(n_params), len(p_params), sharex=True,
sharey=True)
for i in range(3):
for j in range(3):
n = n_params[i]
p = p_params[j]
y = stats.binom(n=n, p=p).pmf(x)
ax[i,j].vlines(x, 0, y, colors='b', lw=5)
ax[i,j].set_ylim(0, 1)
ax[i,j].plot(0, 0, label="n = {:3.2f}\np =
{:3.2f}".format(n, p), alpha=0)
ax[i,j].legend(fontsize=12)
ax[2,1].set_xlabel('$\\theta$', fontsize=14)
ax[1,0].set_ylabel('$p(y|\\theta)$', fontsize=14)
ax[0,0].set_xticks(x)
This book is written for Python version >= 3.5, and it is recommended that you use the most recent version of Python 3 that is currently available, although most of the code examples may also run for older versions of Python, including Python 2.7 with minor adjustments.
Maybe the easiest way to install Python and Python libraries is using Anaconda, a scienti fi c computing distribution. You can read more about Anaconda and download it here. Once Anaconda is in our system, we can install new Python packages with this command:
conda install NamePackage
We will use the following python packages:
- Ipython 5.0
- NumPy 1.11.1
- SciPy 0.18.1
- Pandas 0.18.1
- Matplotlib 1.5.3
- Seaborn 0.7.1
- PyMC3 3.0
If you find an error in the book please fill an issue or send a PR here
• Ipython 5.0 • NumPy 1.11.1 • SciPy 0.18.1 • Pandas 0.18.1 • Matplotlib 1.5.3 • Seaborn 0.7.1 • PyMC3 3.0
