Where can I find mad (mean absolute deviation) in scipy?

Question

It seems scipy once provided a function mad to calculate the mean absolute deviation for a set of numbers:

http://projects.scipy.org/scipy/browser/trunk/scipy/stats/models/utils.py?rev=3473

However, I can not find it anywhere in current versions of scipy. Of course it is possible to just copy the old code from repository but I prefer to use scipy's version. Where can I find it, or has it been replaced or removed?
