A weak bifurcation theory for discrete time stochastic dynamical systems

Diks, Cees G. H.; Wagener, Florian Oskar Ottokar - 2006

This article presents a bifurcation theory of smooth stochastic dynamical systems that are governed by everywhere … of the system. By introducing a weak equivalence notion of these dependence ratios, we arrive at a bifurcation theory for … which in the compact case, the set of stable (non-bifurcating) systems is open and dense. The theory is illustrated with …

How large is average economic growth? : evidence from a robust method

Boswijk, Herman Peter; Franses, Philip Hans - 2001

This paper puts forward a method to estimate average economic growth, andits associated confidence bounds, which does not require a formal decision onpotential unit root properties. The method is based on the analysis of eitherdifference-stationary or trend-stationary time series models,...

Why frequency matters for unit root testing

Boswijk, Herman Peter; Klaassen, Franc - 2004 - Rev.

It is generally believed that for the power of unit root tests, only the time span and not the observation frequency matters. In this paper we show that the observation frequency does matter when the high-frequency data display fat tails and volatility clustering, as is typically the case for...

Spot variance path estimation and its application to high frequency jump testing

Bos, Charles S.; Janus, Paweł; Koopman, Siem Jan - 2009

This paper considers spot variance path estimation from datasets of intraday high frequency asset prices in the presence of diurnal variance patterns, jumps, leverage effects and microstructure noise. We rely on parametric and nonparametric methods. The estimated spot variance path can be used...

Spurious regression, cointegration, and near cointegration : a unifying approach

Haldrup, Niels; Jansson, Michael - 1999

This paper introduces a representation of an integrated vectortime series in which the coefficient of multiple correlation computed fromthe long-run covariance matrix of the innovation sequences is a primitiveparameter of the model. Based on this representation, a notion of nearcointegration is...

Maximum likelihood estimation for correctly specified generalized autoregressive score models : feedback effects, contraction conditions and asymptotic properties

Blasques, Francisco; Koopman, Siem Jan; Lucas, André - 2014

. To illustrate the results, we apply the theory to a number of empirically relevant models. …

Model-based estimation of high frequency jump diffusions with microstructure noise and stochastic volatility

Bos, Charles S. - 2008

When analysing the volatility related to high frequency financial data, mostly non-parametric approaches based on realised or bipower variation are applied. This article instead starts from a continuous time diffusion model and derives a parametric analog at high frequency for it, allowing...

Flexible mixture-amount models for business and industry using Gaussian processes

Ruseckaite, Aiste; Fok, Dennis; Goos, Peter - 2016

Many products and services can be described as mixtures of ingredients whose proportions sum to one. Specialized models have been developed for linking the mixture proportions to outcome variables, such as preference, quality and liking. In many scenarios, only the mixture proportions matter for...
