Damped least square method
Webmethod of least squares corresponds to w- > oo , and is thus a special case of the method here given, which may be termed the method of "damped least squares." If we denote the number of parameters by k, it is seen from the determinantal solution of equations (10) that, in the neighborhood of w = Q, - [a0 'wl~kbcd Aa = aw - ao = w~kabc whence ...

WebIn this study, data on the poverty rate in Maluku Province in 2005-2024 were used. This research process uses the exponential smoothing method, which is used to predict the poverty rate in Maluku Province in 2024-2025. The best method for forecasting poverty levels in Maluku Province is the Holt Linear Trend. WebA general approach to solving the problem of discontinuity of the pseudoinverse solution at a singular configuration is to use the damped least-squares method, which is known as the Levenberg-Marquardt stabilization method [Wampler 86], [Nakamura 87]. This solution minimizes the following expression:
