Testsuite
=========
This directory contains input data for the testsuite. In the future,
we should also write a testsuite based on the data.
Input data
----------
Below is a description of the input data for the testsuite.
* The data files ``discrete_data.txt`` and ``continuous_data.txt`` are the
original example files from Aaron Clauset's own implementation of the
power law fitting method. Fitting ``discrete_data.txt`` should result in
alpha = 2.58, xmin = 2 and a log-likelihood of -9155.63. Fitting
``continuous_data.txt`` should yield alpha=2.53282, xmin=1.43628 and
a log-likelihood of -9276.42.
* The data files ``celegans-indegree.dat``,
``celegans-outdegree.dat``, and ``celegans-totaldegree.dat`` contain
the in-degree, out-degree, and total degree sequences, respectively,
of the neural network of the C. elegans. The degree sequences are
computed from the dataset compiled by [WattsStrogatz1998]_, who in
turn obtained the dataset from original experimental data by
[WhiteEtAl1986]_.
* The data file ``condmat2005-degree.dat`` contains the 2005 update of
the collaboration network of scientists posting preprints on the
condensed matter archive at www.arxiv.org. The network is weighted,
with weights assigned as described in [Newman2001a]_. The data
should be cited as an updated version of the dataset used in
[Newman2001b]_. The network is undirected and we assume it has no
self-loops nor multiple edges. The degree sequence reflects these
assumptions.
* The data file ``karate.dat`` contains the (total) degree sequence of
the Zachary karate club network, as described in [Zachary1977]_.
* The data files ``karate-commented.dat``, ``karate-commented_dos.dat``,
and ``karate-commented_corrupted.dat`` are *commented* version of the
data file ``karate.dat``. Inline comments with a single # (hash) as
left delimiter are supported: all the text from the ASCII character #
(35) to the end of the line is ignored. The first data file mainly
serves as illustration; the two others, with a self-explanatory
subscript, are mainly meant for testing.
