On the use of L-functionals in regression models

open access: yesOpen Mathematics, 2023
In this article, we survey and unify a large class or LL-functionals of the conditional distribution of the response variable in regression models.

Effect of Allocated Radiotherapy after Breast Surgeries over Death Risk in Early Breast Cancer Patients: A Meta‐Analysis

open access: yesComputational and Mathematical Methods in Medicine, Volume 7, Issue 1, Page 45-51, 2006., 2006
Meta‐analysis is a widely used tool to synthesize the results of a set of primary studies leading to more powerful conclusions than those provided by isolated ones. To evaluate the effect of allocated radiotherapy, types of breast surgery and other risk factors over death risk in early breast cancer patients, we carried out a meta‐analysis using ...

Identification of causal intervention effects under contagion

open access: yesJournal of Causal Inference, 2021
Defining and identifying causal intervention effects for transmissible infectious disease outcomes is challenging because a treatment – such as a vaccine – given to one individual may affect the infection outcomes of others. Epidemiologists have proposed

Comparison of Different Underlying Distributions in The Accelerated Failure Time (AFT) Model on Mortality of Covid-19 Patients

open access: yesInPrime, 2022
In 2022, the COVID-19 virus is still making headlines in various mass media because it is a virus that is very dangerous to health. The world health organization, WHO, explained that the virus caused a global pandemic that infected the whole world.

An Equilibrium Assembly Model Applied to Murine Polyomavirus

open access: yesComputational and Mathematical Methods in Medicine, Volume 6, Issue 2, Page 91-93, 2005., 2005
In Keef et al., Assembly Models for Papovaviridae based on Tiling Theory (submitted to J. Phys. Biol.), 2005 [1] we extended an equilibrium assembly model to the (pseudo–)T = 7 viral capsids in the family of Papovaviridae providing assembly pathways for the most likely or primary intermediates and computing their concentrations.

The Architecture of Viral Capsids Based on Tiling Theory

open access: yesComputational and Mathematical Methods in Medicine, Volume 6, Issue 2, Page 87-90, 2005., 2005
A vital constituent of a virus is its protein shell, called the viral capsid, that encapsulates and hence protects the viral genome. The surface structures of a large number of icosahedral viruses can be modelled via Caspar‐Klug Theory, which has hence become one of the fundamental concepts in virology. However, growing experimental evidence have shown

A Stochastic Model of Icosahedral Capsid Growth

open access: yesComputational and Mathematical Methods in Medicine, Volume 6, Issue 2, Page 95-97, 2005., 2005
A model of growth of icosahedral capsids is proposed. It is similar to the stochastic model of fullerene growth, but takes into account variations in the composition of pentamers and hexamers that are responsible for the final capsid size. We show that the observed high yield of capsid production implies a high level of self‐organization of the ...

Analyzing high dimensional correlated data using feature ranking and classifiers

open access: yesComputational and Mathematical Biophysics, 2019
The Illumina Infinium HumanMethylation27 (Illumina 27K) BeadChip assay is a relatively recent high-throughput technology that allows over 27,000 CpGs to be assayed.

Generalized distributions of order k associated with success runs in Bernoulli trials

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2003, Issue 13, Page 801-815, 2003., 2003
In a sequence of independent Bernoulli trials, by counting multidimensional lattice paths in order to compute the probability of a first‐passage event, we derive and study a generalized negative binomial distribution of order k, type I, which extends to distributions of order k, the generalized negative binomial distribution of Jain and Consul (1971 ...

Causal effect on a target population: A sensitivity analysis to handle missing covariates

open access: yesJournal of Causal Inference, 2022
Randomized controlled trials (RCTs) are often considered the gold standard for estimating causal effect, but they may lack external validity when the population eligible to the RCT is substantially different from the target population.
