Hi All!
I have implemented multiple regression in a following way:
def multipleRegression(x, y):
Perform linear regression using least squares method.
X - matrix containing inputs for observations,
y - vector containing one of outputs for every observation

I am using it on large number of observations so it is common to have
x matrix of about 5000x20 and y vector of length 5000, and more.
I also have to run that multiple times for different y vectors and
same x matrix.
Just make a matrix y such

You should be using QR or SVD for this.
