Estimating predicted probabilities from logistic regression: different methods correspond to different target populations.

open access: yesInternational Journal of Epidemiology, 2014
BACKGROUND We review three common methods to estimate predicted probabilities following confounder-adjusted logistic regression: marginal standardization (predicted probabilities summed to a weighted average reflecting the confounder distribution in the ...

Longitudinal predictors of weapon involvement in middle adolescence: Evidence from the UK Millennium Cohort Study

open access: yesAggressive Behavior, Volume 49, Issue 1, Page 5-14, January 2023., 2023
Abstract This study uses longitudinal data from the UK Millennium Cohort Study (N = 13,277) to examine the childhood and early adolescence factors that predict weapon involvement in middle adolescence, which in this study is exemplified by having carried or used a weapon.

COMP Report: CPQR technical quality control guidelines for use of positron emission tomography/computed tomography in radiation treatment planning

open access: yesJournal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022
Abstract Positron emission tomography with x‐ray computed tomography (PET/CT) is increasingly being utilized for radiation treatment planning (RTP). Accurate delivery of RT therefore depends on quality PET/CT data. This study covers quality control (QC) procedures required for PET/CT for diagnostic imaging and incremental QC required for RTP.

Liquefaction of Tangier soils by using physically based reliability analysis modelling

open access: yesMATEC Web of Conferences, 2012
Approaches that are widely used to characterize propensity of soils to liquefaction are mainly of empirical type. The potential of liquefaction is assessed by using correlation formulas that are based on field tests such as the standard and the cone ...

Viabilité, probabilités, induction

open access: yesTracés, 2013
While probability calculus helps favour the credence in a future occurrence, operational research prescribes a list of controls aimed at a given objective, generally in optimizing a given criterion.

Probabilities from envariance?

open access: yes, 2004
Zurek claims to have derived Born's rule noncircularly in the context of an ontological no-collapse interpretation of quantum states, without any "deus ex machina imposition of the symptoms of classicality." After a brief review of Zurek's derivation it ...

Monte Carlo transition probabilities [PDF]

open access: yes, 2001
Transition probabilities governing the interaction of energy packets and matter are derived that allow Monte Carlo NLTE transfer codes to be constructed without simplifying the treatment of line formation.

Uniqueness of radiomic features in non‐small cell lung cancer

open access: yesJournal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022
Abstract Purpose The uniqueness of radiomic features, combined with their reproducibility, determines the reliability of radiomic studies. This study is to test the hypothesis that radiomic features extracted from a defined region of interest (ROI) are unique to the underlying structure (e.g., tumor). Approach Two cohorts of non‐small cell lung cancer (
