Package: python-scipy
Version: 0.7.2+dfsg1-1
Severity: normal
Applying scipy.stats.kde.gaussian_kde to a list of integers, e.g. [1,2,3,4,5],
is not same as applying it to a list of floats [1.0, 2.0, 3.0, 4.0, 5.0]. This
is quite surprising and should probably be fixed. The output for integers
appears to be always 0, although I did not test with very wide range of inputs.
This is probably a bug in the internals of gaussian_kde, since it probably
converts the input into a NumPy array without specifying the type, and then
does math on it expecting it to be an array of floats, whereas it will be an
array of some integral type if input is all-integral.
Converting input to floating point types manually allows one to work around
this issue.
Expected:
python -c 'import scipy.stats;l=[1,2,3,3,3,3,4,5];k=[1,2,3,4,5];print
scipy.stats.kde.gaussian_kde(l)(k) == scipy.stats.kde.gaussian_kde(map(float,
l))(k)' to print [True True True True True]
Actual:
python -c 'import scipy.stats;l=[1,2,3,3,3,3,4,5];k=[1,2,3,4,5];print
scipy.stats.kde.gaussian_kde(l)(k) == scipy.stats.kde.gaussian_kde(map(float,
l))(k)' prints [False False False False False]
