comment Simple Least Squares Regression?
I've written code for this at: codereview.stackexchange.com/questions/10122/…. Can you check it please.

comment pseudo-random permutation of $[0,N)$
Yes, typo. What is the significance of (sqrt(5) - 1)/2 here? Why is your choice of x and k superior to any other?

comment pseudo-random permutation of $[0,N)$
Is it so that for any x relatively prime to n and for any k, that (k,x+k,2x+k,3x+k,...,(n-1)+k) mod (n,n,...,n) is a permutation of (0,1,2,...,n-1) ?

comment pseudo-random permutation of $[0,N)$
I mean O(1) time/space per call to f, so yes O(N)/O(1) time/space for the whole permutation.

comment pseudo-random permutation of $[0,N)$
N is very large, I would prefer a solution in O(1) space and O(1) time if possible.
