numpy.linalg.lstsq equivalent in Apache Commons Math Java library?

I have the following call to numpy.linalg.lstsq:

http://docs.scipy.org/doc/numpy/reference/generated/numpy.linalg.lstsq.html

x = [[ 0.69314718] [ 1.09861229] [ 1.38629436] [ 1.60943791] [ 1.79175947] [ 1.94591015]]

y = [ 0. 0.20273255 0.5815754 0.7520387 0.96885669 1.09861229]

l = numpy.linalg.lstsq(x, y)

which returns

l -> tuple: (array([ 0.46323573]), array([ 0.25872885]), 1, array([ 3.63269497]))

Could somebody point out the equivalent function (if available) in

http://commons.apache.org/math/

(or possibly in some other Java math library ...)
