For notational simplicity the variable J will be used for [∂yˆ/∂p]. Note that in models that are linear in the parameters, yˆ = Xp, the Jacobian [∂yˆ/∂p] is the matrix of model basis vectors X.

In mathematics and computing, the Levenberg–Marquardt algorithm (LMA or just LM), also known as the damped least-squares (DLS) method, is used to solve non-linear least squares problems. These minimization problems arise especially in least squares curve fitting. The LMA interpolates between the … See more The primary application of the Levenberg–Marquardt algorithm is in the least-squares curve fitting problem: given a set of $${\displaystyle m}$$ empirical pairs See more • Moré, Jorge J.; Sorensen, Daniel C.
