In these cases it is possible to find a best-fit solution that minimizes . A particularly common choice of p is 2; this generates a least squares solution. These are often used because the function is differentiable in and because the 2-norm is preserved under orthogonal transformations.

CiteSeerX - Document Details (Isaac Councill, Lee Giles): In this paper, we investigate a top-down design strategy for reducing the number of operations in digital filters based on a constrained least squares (CLS) solution. ... We also show that for filters designed using least squares (LS) method, the solution obtained...

(X-t)y = (X-t)XB and we solve for B, which is the inverse of (X-t)X times (X-t)y. This vector contains the intercept and the coefficients for the least squares solution. Done!
