Modified Jacobian matrix at the solution, in the sense that J^T J is a Gauss-Newton approximation of the Hessian of the cost function. The type is the same as the one used by the algorithm. This can be used to estimate the Covariance Matrix of the parameters using the following formula:...
A general-purpose root-finding algorithm such as Newton-Raphson is usually suitable.The code below compares the naive ordinary least squares fit on some sample log-transformed data with the above nonlinear fit. In the figures below, the contours are of values of r2(a,b)r2(a,b), decreasing...
Numerical results show the advantages of our model on the test set considered, and the derivative-free algorithms based on our least |$H^{2}$| norm updating quadratic model functions can solve test problems with fewer function evaluations than the algorithm based on the least Frobenius norm ...

Since partial least squares (PLS) is the soft sensor algorithm used to evaluate the performance of the variable selection methods, and in fact several methods evaluated in this work are also based on PLS, here we briefly review the PLS algorithm. PLS is a well-known multivariate statistical te...
