Damped least-squares method
Webthe damped least squares (DLS) method. For an extension of the DLS methods to a method called selectively damped least squares (SDLS), see 2. Buss and Kim [7]. Nearly all the present paper is expository, but new aspects include the possibility of forming the Jacobian matrix with the WebJan 24, 2024 · The method of least squares is a statistical procedure for determining the best fit line for a group of data points by reducing the total of the points’ offsets or residuals from the plotted curve. The method of least squares regression is utilised to predict the behaviour of dependent variables.

WebThe three least-squares normal equations for hypocentral coordinates, with diagonal terms equal to one, are then solved iteratively by adding a variable damping factor, θ 2, to their diagonal terms before inversion. If the residual sum of squares increases, we return to the previous iteration, increase θ 2, then try again. This procedure ...
