The Computational Complexity of Estimating Convergence Time [PDF]

, 2010
An important problem in the implementation of Markov Chain Monte Carlo algorithms is to determine the convergence time, or the number of iterations before the chain is close to stationarity. For many Markov chains used in practice this time is not known.

Measuring the Impact of the Substitution of Innovator Biologics With Biosimilars on Uptake and Costs Among Ontario Public Drug Benefit Recipients

Clinical Pharmacology &Therapeutics, EarlyView.
In Ontario, biologics have historically represented a small proportion of public drug claims but a large proportion of spending. Biosimilars, lower cost alternatives to biologics, offer a potential solution to the rising spending on biologics. From March 2023 to January 2024, the Ontario Ministry of Health required public drug program beneficiaries on ...

Sustainable Development, Environmental Certification and the Financial Performance of the Road Passenger Transportation Sector

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Within the framework of sustainable development and environmental policy, environmental certification is regarded as a mechanism through which road passenger transport companies (RPTCs) could mitigate their adverse environmental impacts and attain competitive advantages that may enhance their financial performance.

On the Autocorrelation and Stationarity of Multi-Scale Returns

Mathematics
In this article, we conduct a statistical analysis of the autocorrelation functions (ACF) of multi-scale logarithmic returns computed over maximal monotonic uninterrupted trends (runs) in financial indices’ daily data. We analyze the Dow Jones Industrial

Non‐stationary forest responses to hotter droughts: a temporal perspective considering the role of past legacies

Ecography, EarlyView.
Global change is altering forests worldwide, with multiple consequences for ecosystem functioning. Temporal changes in climate, and extreme, compounded weather events like hotter droughts are affecting the demography, composition and function of forests, leading to a highly uncertain future.

Flexible methods for species distribution modeling with small samples

Ecography, EarlyView.
Species distribution models (SDMs) predict where species live or could potentially live and are a key resource for ecological research and conservation decision‐making. However, current SDM methods often perform poorly for rare or inadequately sampled species, which include most species on earth, as well as most of those of the greatest conservation ...

Wavelet-based estimators of partial derivatives of a multivariate density function for discrete stationary and ergodic processes

AIMS Mathematics
In this work, we propose a wavelet-based framework for estimating the derivatives of a density function in the setting of discrete, stationary, and ergodic processes.

“On a skinny horse in bad weather…”: the problem of availability of land medical care in Russia at the turn of the 19th and 20th centuries (according to the data of the Tula province)

Studia Humanitatis, 2022
The article discusses the evolution of “accessibility” concept in zemstvo medicine at the turn of the 19th and 20th centuries. The main theoretical approaches to the definition of this concept at different stages of the development of medical thought are

Projection estimators for autoregressive panel data models [PDF]

In this paper we explore a new approach to estimation for autoregressive panel data models, based on projecting the unobserved individual effects on the vector of observations on the lagged dependent variable.
