Regression models for grouped survival data: Estimation and sensitivity analysis
(ELSEVIER SCIENCE BV, 2011)
In this study, regression models are evaluated for grouped survival data when the effect of censoring time is considered in the model and the regression structure is modeled through four link functions. The methodology for ...
Towards an intelligent graphical interface for linear programming modelling
(1996-12-01)
The increase of computing power of the microcomputers has stimulated the building of direct manipulation interfaces that allow graphical representation of Linear Programming (LP) models. This work discusses the components ...
Comparison of friction models applied to a control valve
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
Eight different models to represent the effect of friction in control valves are presented: four models based on physical principles and four empirical ones. The physical models, both static and dynamic, have the same ...
A Generalized Log-Normal Model for Grouped Survival Data
(Taylor & Francis Inc, 2010-01-01)
It is common to have experiments in which it is not possible to observe the exact lifetimes but only the interval where they occur. This sort of data presents a high number of ties and it is called grouped or interval-censored ...
THE LOG-BURR XII REGRESSION MODEL FOR GROUPED SURVIVAL DATA
(TAYLOR & FRANCIS INCPHILADELPHIA, 2012)
The log-Burr XII regression model for grouped survival data is evaluated in the presence of many ties. The methodology for grouped survival data is based on life tables, where the times are grouped in k intervals, and we ...
LEGISLATIVE LINKED OPEN DATA: a proposal of linked open data modelling for legislative information
(Univ Federal Campina Grande, 2018-05-01)
This research aimed to create a linked open data (LOD) model using RDF (Resource Description Framework) for a legislative dataset from the House of Representatives. It has proceeded a literature review embracing the concepts ...
Joint species movement modeling: how do traits influence movements?
(2019-04-01)
Joint species distribution modeling has enabled researchers to move from species-level to community-level analyses, leading to statistically more efficient and ecologically more informative use of data. Here, we propose ...
Modeling grouped survival data with time-dependent covariates
(Taylor & Francis Inc, 2006-10-01)
In this article, proportional hazards and logistic models for grouped survival data were extended to incorporate time-dependent covariates. The extension was motivated by a forestry experiment designed to compare five ...
The generalized log-gamma mixture model with covariates: local influence and residual analysis
(SPRINGER HEIDELBERG, 2009)
In a sample of censored survival times, the presence of an immune proportion of individuals who are not subject to death, failure or relapse, may be indicated by a relatively high number of individuals with large censored ...
The impact of the IFLA Library Reference Model on cataloging practice: use cases, advantages and disadvantages
(Univ Federal Rio Grande Sul, Fac Biblioteconomia & Comunicacao, 2021-01-01)
The IFLA Library Reference Model (IFLA LRM) is a high-level conceptual model that arises from the need to consolidate the three models of the FR Family, the demands of the current technological context and compatibility ...
