Statistical Emulation of Large Linear Dynamic Models

  title={Statistical Emulation of Large Linear Dynamic Models},
  author={Peter C. Young and Marco Ratto},
The article describes a new methodology for the emulation of high-order, dynamic simulation models. This exploits the technique of dominant mode analysis to identify a reduced-order, linear transfer function model that closely reproduces the linearized dynamic behavior of the large model. Based on a set of such reduced-order models, identified over a specified region of the large model’s parameter space, nonparametric regression, tensor product cubic spline smoothing, or Gaussian process… CONTINUE READING
