Frontiers in Neuroscience, 2023 BackgroundAging is a significant risk factor for many neurodegenerative diseases and neurological tumors. Previous studies indicate that the frailty index, facial aging, telomere length (TL), and epigenetic aging clock acceleration are commonly used ...

Statistical Analysis of Message Delay in SIP Proxy Server
Journal of Telecommunications and Information Technology, 2014 Single hop delay of SIP message going through SIP proxy server operating in carriers backbone network is being analyzed. Results indicate that message sojourn times inside SIP server in most cases do not exceed order of tens of milliseconds (99% of all SIP-I messages experience less than 21 ms of sojourn delay) but there were observed very large delays

Building Statistical Proxy Models for CO2 Geologic Sequestration
Energy Procedia, 2014 AbstractWe compare two approaches for building a statistical proxy model (metamodel) for CO2 geologic sequestration from the results of full-physics compositional simulations. The first approach involves a classical Box-Behnken experimental design with a quadratic polynomial response surface.

Proxy Expenditure Weights for Consumer Price Index: Audit Sampling Inference for Big-Data Statistics [PDF]
Journal of the Royal Statistical Society Series A: Statistics in Society, 2020 AbstractPurchase data from retail chains can provide proxy measures of private household expenditure on items that are the most troublesome to collect in the traditional expenditure survey. Due to the inevitable coverage and selection errors, bias must exist in these proxy measures.

Detecting instabilities in tree-ring proxy calibration [PDF]
Climate of the Past, 2010 Evidence has been found for reduced sensitivity of tree growth to temperature in a number of forests at high northern latitudes and alpine locations. Furthermore, at some of these sites, emergent subpopulations of trees show negative growth trends with ...

Global comparison of cancer outcomes: standardization and correlation with healthcare expenditures
BMC Public Health, 2019 Background Cancer outcomes vary widely among different countries. However, comparisons of cost-effectiveness and cost-efficiency of different systems are complex because the incidences of different cancers vary across countries and their chances of cure ...

A statistical framework for integrating nonparametric proxy distributions into geological reconstructions of relative sea level [PDF]
Advances in Statistical Climatology, Meteorology and Oceanography, 2022 Abstract. Robust, proxy-based reconstructions of relative sea-level (RSL) change are critical to distinguishing the processes that drive spatial and temporal sea-level variability. The relationships between individual proxies and RSL can be complex and are often poorly represented by traditional methods that assume Gaussian likelihood distributions. We

A few prospective ideas on climate reconstruction: from a statistical single proxy approach towards a multi-proxy and dynamical approach [PDF]
Climate of the Past, 2009 Abstract. Important progresses have been made in palaeoclimatological studies by using statistical methods. But they are in somewhere limited as they take the present as an absolute reference. This is particularly true for the modern analogue technique.
