The weighted median does not appear to be correct, e.g.:

>import weighted as w
>w.median(array([1,2,3]),array([100,1,1]))
1.0198019801980198

Shouldn't the weighted median be an element of the data array:
https://en.wikipedia.org/wiki/Weighted_median

Is there another definition of weighted median?

Create tests to check that the deprecation warning is raised when importing weighted

For your consideration:

This may be obvious in hindsight, but to use wquantiles, you have to import weighted. Not import wquantiles or from wquantiles import .... This is a bit counter-intuitive and not explicitly documented. Took me a while to figure out why python setup.py install was successful but python -c 'import wquantiles' was not.

I do not have any particular problem with doing the import the way it is now, but I think it should be mentioned somewhere in README.md.

Not sure about this, as I haven't used Python in a while and hence might be doing something wrong, but currently doing pip install wquantiles just adds a a folder named wquantiles-0.3.dist-info to my package folder, which doesn't contain the actual .py files that define the functions.

Hello,

I am trying to apply the following simple code

wquantiles.median([1,2,3,4,5], weights = [0.15, 0.1, 0.2, 0.3, 0.25])

Unfortunately, I have the following error:

---------------------------------------------------------------------------

AttributeError: 'list' object has no attribute 'ndim'

Could you help me please? I could not find any documentation.

Would it be possible if you could please upload the newest version to pip? I want to package something which depends on this.
