Ellipsoid‐Based Interval‐Type Uncertainty Model Updating Based on Riemannian Manifold and Gaussian Process Model

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Modern engineering systems require advanced uncertainty‐aware model updating methods that address parameter correlations beyond conventional interval analysis. This paper proposes a novel framework integrating Riemannian manifold theory with Gaussian Process Regression (GPR) for systems governed by Symmetric Positive‐Definite (SPD) matrix ...

Specification Testing of Markov Switching Models*

open access: yesOxford Bulletin of Economics and Statistics, 2003
AbstractThis paper proposes a set of formal tests to address the goodness‐of‐fit of Markov switching models. These formal tests are constructed as tests of model consistency and of both parametric and non‐parametric encompassing. The formal tests are then combined with informal tests using simulation in combination with non‐parametric density and ...

Reconsidering Volume‐Based Drug Procurement Policy: The Consequences of Manufacturers' Optimal Production Planning and Breach Strategies

open access: yesNaval Research Logistics (NRL), EarlyView.
ABSTRACT This paper examines the impacts of Volume‐Based Procurement (VBP) policies on pharmaceutical supply chains, with a focus on the strategic behaviors of manufacturers. VBP aims to reduce costs and stabilize supplies by centralizing procurement through competition based on volumes and prices.

Pemodelan Deteksi Dini Krisis Mata Uang Berdasarkan Indiktor Nilai Tukar Nominal

open access: yesMajalah Ilmiah Bijak, 2019
The financial crisis by definition is a situation where several financial assets lose most of their nominal value. The financial crisis experienced by Indonesia in 1997 had a severe impact on the Indonesian economy, so a model was needed to detect this ...

The effects of seasonality and parasitism on diet and habitat selection in the common periwinkle

open access: yesOikos, EarlyView.
The common periwinkle Littorina littorea is an ecologically important grazer, known for its strong influence on algal communities and its role in structuring ecosystems. It serves as the first intermediate host for several trematode species in the Baltic Sea, especially for the fluke Cryptocotyle lingua.

Measuring Business Cycle Turning Points in Japan with a Dynamic Markov Switching Factor Model [PDF]

open access: yes
In the dynamic factor model, a single unobserved factor common to some macroeconomic variables is defined as a composite index to measure business cycles.

An objective Bayesian method for including parameter uncertainty in ensemble model output statistics

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Conventional model output statistics and ensemble model output statistics methods for calibrating ensemble forecasts lead to severe underestimation of the probabilities of ensemble extremes (in blue). This is because they ignore statistical parameter uncertainty.

Impacts of Korea's Exchange Rate Uncertainty on Exports

open access: yesEast Asian Economic Review, 2003
This paper examines the effects of two types of uncertainty related to the real effective exchange rate (REER) in Korea for export trends. To decompose uncertainties into two types of component, I propose an advanced generalized Markov switching model ...
