General State-Space Models

by Arnaud Doucet , 2011
"... State-space models also known as Hidden Markov models are ubiquitous time series models in ecology, econometrics, engineering, statistics etc. Let fXngn1 be a latent/hidden Markov process de…ned by X1 µθ () and Xn j (Xn1 = xn1) fθ ( j xn1). We only have access to a process fYngn1 such that, condi ..."

Switching State-Space Models

by Zoubin Ghahramani, Geoffrey E. Hinton - King’s College Road, Toronto M5S 3H5 , 1996
"... We introduce a statistical model for times series data with nonlinear dynamics which iteratively segments the data into regimes with approximately linear dynamics and learns the parameters of each of those regimes. This model combines and generalizes two of the most widely used stochastic time se ..."

, in which both expert and gating networks are recurrent. Inferring the posterior probabilities of the hidden states of this model is computationally intractable, and therefore the exact Expectation Maximization (EM) alogithm cannot be applied. However, we present a variational approximation which

Resampling in State Space Models ∗

by David S. Stoffer, Kent D. Wall
"... Abstract. Resampling the innovations sequence of state space models has proved to be a useful tool in many respects. For example, while under general conditions, the Gaussian MLEs of the parameters of a state space model are asymptotically normal, several researchers have found that samples must be ..."

Wavelets in State Space Models

by Eliana Zandonade And, Eliana Z, Pedro A. Morettin
"... In this paper we consider the utilization of wavelets in conjunction with state space models. Specifically, the parameters in the system matrix are expanded in wavelet series and estimated via the Kalman Filter and the EM algorithm. In particular this approach is used for switching models. Two appli ..."

Fitting State Space Models with EViews

by unknown authors
"... This paper demonstrates how state space models can be fitted in EViews. We first briefly introduce EViews as an econometric software package. Next we fit a local level model to the Nile data. We then show how a multivariate “latent risk ” model can be developed, making use of the EViews programming ..."
