Abstract: | This paper proposes a method to seek initial distributions of parameters for a self-organizing state space model proposed
by Kitagawa (J Am Stat Assoc 93:1203–1215, 1998). Our method is based on the simplex Nelder–Mead algorithm for solving nonlinear
and discontinuous optimization problems. We show the effectiveness of our method by applying it to a linear Gaussian model,
a linear non-Gaussian model, a nonlinear Gaussian model, and a stochastic volatility model. |
