I wish to report the following bug.

Scipy v.11 library in python2.7 gives spearmanrcorrel([1,2,3,4,5],[5,6,7,8,7]) = 0.8207 while scipy v.6 in python2.5 gives spearmanr([1,2,3,4,5],[5,6,7,8,7]) = 0.825(which is correct according to spearman correlation formula).

The spearman correlation for [1,2,3,4,5],[5,6,7,8,7] calculated online according to formula available at : https://statistics.laerd.com/calculators/spearmans-rank-order-correlation-ca..., also gives 0.825.

--The definition of spearmanr function in Scipy v.11 is given at : http://docs.scipy.org/doc/scipy/reference/generated/scipy.stats.spearmanr.ht....

Thanks, - Om Damani
