Prognostic Impact of Anterior Commissure Involvement on Treatment Failure in Early‐Stage Glottic Carcinoma Treated With Definitive Radiotherapy: A Univariate and Multivariate Meta‐Analysis

Head &Neck, EarlyView.
ABSTRACT Background Early‐stage glottic carcinoma is characterized by high cure rate, but about 10% of patients still develop local recurrence after radiotherapy (RT). Although advances in local therapies have markedly improved larynx preservation, anterior commissure involvement (ACI) may worsen outcomes yet remains insufficient to fully guide ...

Application of Markov chain Monte Carlo and machine learning for identifying active modules in biological graphs

Научно-технический вестник информационных технологий, механики и оптики
In biology, information about interactions between the proteins or genes under study can be represented as a biological graph. A connected subgraph, whose vertices perform a common biological function, is called an active module.

Bayesian state-space models with multiple CPUE data: the case of a mullet fishery

Scientia Marina, 2017
We propose a novel Bayesian hierarchical structure of state-space surplus production models that accommodate multiple catch per unit effort (CPUE) data of various fisheries exploiting the same stock.

Quantum Speedups for Multiproposal MCMC. [PDF]

Bayesian Anal
Multiproposal Markov chain Monte Carlo (MCMC) algorithms choose from multiple proposals to generate their next chain step in order to sample from challenging target distributions more efficiently. However, on classical machines, these algorithms require $\mathcal{O}(P)$ target evaluations for each Markov chain step when choosing from $P$ proposals ...

MCMC METHODS FOR DIFFUSION BRIDGES [PDF]

Stochastics and Dynamics, 2008
We present and study a Langevin MCMC approach for sampling nonlinear diffusion bridges. The method is based on recent theory concerning stochastic partial differential equations (SPDEs) reversible with respect to the target bridge, derived by applying the Langevin idea on the bridge pathspace.

Forecasting Related Time Series

Journal of Applied Econometrics, EarlyView.
ABSTRACT A collection of time series are “related” if they follow similar stochastic processes and/or they are statistically dependent. This paper proposes a related time series (RTS) forecasting model that exploits these relationships. The model's foundation is a set of univariate Gaussian autoregressions, one for each series, which are then augmented

Simple reparameterization to improve convergence in linear mixed models

Acta Agriculturae Slovenica, 2010
Slow convergence and mixing are one of the main problems of Markov chain Monte Carlo (McMC) algorithms applied to mixed models in animal breeding. Poor convergence is to a large extent caused by high posterior correlation between variance components and ...

Nonasymptotic bounds on the mean square error for MCMC estimates via renewal techniques [PDF]

, 2010
The Nummellin’s split chain construction allows to decompose a Markov chain Monte Carlo (MCMC) trajectory into i.i.d. "excursions". Regenerative MCMC algorithms based on this technique use a random number of samples.

Monetary Policy Shocks and Exchange Rate Dynamics in Small Open Economies

Journal of Applied Econometrics, EarlyView.
ABSTRACT This paper investigates whether the effects of monetary policy shocks on real exchange rates have changed over time and, if so, whether these changes stem from shifts in transmission mechanisms or from variation in the volatility of the shocks themselves.

Evaluation of fall‐seeded cover crops for grassland nesting waterfowl in eastern South Dakota

Wildlife Society Bulletin, EarlyView., 2023
Cover crops are experiencing a revival among Midwestern farmers, and we assessed their attractiveness and safety for nesting ducks in South Dakota. Nest success was markedly lower in cover crops than in perennial cover during both years of our study, including 2019 which was a best‐case scenario for cover crops, with extremely wet conditions delaying ...
