I was only looking at wikipedia, (I dowloaded the papers a while ago but never read them) https://github.com/PyMVPA/PyMVPA/blob/master/mvpa2/misc/dcov.py#L160 looks like a double sum, but wikipedia only has one sum, elementwise product. When you have a nice implementation, I will (try to) borrow it :) Josef > > ;) > > On Fri, 15 Jun 2012, [email protected] wrote: >> >>> here is my attempt: >> >>> >> >>> [1]https://github.com/satra/scikit-learn/blob/enh/covariance/sklearn/covariance/distance_covariance.py >> >>> i'll look at your code in detail later today to understand the uv=True > >> > trying to see how well this works, here's my gist >> > https://gist.github.com/2938402 >> (univariate only) > >> > bretzel and cosine have essentially zero distance correlation ?? > > -- > Yaroslav O.
