Hello, I am using the Strassen algorithm for matrix multiplication inside my multiple linear regression solver, so what about its numerical stability ? Read this: "We begin by discussing Strassen-like algorithms, based on recursive partitioning of matrices into the same number of blocks. We prove that all such algorithms are stable" Read the following paper: http://www.cs.cornell.edu/~rdk/papers/matmul.pdf Thank you, Amine Moulay Ramdane.

Hello, I am also using LU factorization to compute the inverse matrix inside my multiple linear regression solver, so what about its numerical stability ? Read this: "The LU factorization is numerically stable in practice, and produces a reasonable growth factor." Read here on 3.1: http://www.netlib.org/lapack/lawnspdf/lawn259.pdf Amine Moulay Ramdane.
