Gaussianity Tests
-----------------
Figure 4.7.

The results of the Anderson-Darling test, the Kolmogorov-Smirnov test, and the
Shapiro-Wilk test when applied to a sample of 10,000 values drawn from a normal
distribution (upper panel) and from a combination of two Gaussian distributions
(lower panel).

The functions are available in the ``scipy`` package:

- The Anderson-Darling test (``scipy.stats.anderson``)
- The Kolmogorov-Smirnov test (``scipy.stats.kstest``)
- The Shapiro-Wilk test (``scipy.stats.shapiro``)
