WebBoth Wilson-θ and Newmark-β methods are generally used approaches for solving numerical solutions of dynamical systems [1]-[6]. As we know, a fundamental assumption of the Wilson-θ method lies in that, the acceleration changes linearly in a single time step [7]. For this reason, the Wilson-θ is considered to be one of linear acceleration ... WebMay 3, 2024 · The Theta method was the winner of the M3 forecasting competition. It combines a damped linear trend model with a Simple Exponential Smoother.
