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 ...
A note on model uncertainty in linear regression
(Blackwell Publ Ltd, 2003-01-01)
We consider model selection uncertainty in linear regression. We study theoretically and by simulation the approach of Buckland and co-workers, who proposed estimating a parameter common to all models under study by taking ...
Fractional polynomial response surface models
Second-order polynomial models have been used extensively to approximate the relationship between a response variable and several continuous factors. However, sometimes polynomial models do not adequately describe the ...
Subjective modeling decisions can significantly impact the simulation of flood and drought events
(Elsevier B.V., 2019)
© 2018 The Author(s)It is generally acknowledged in the environmental sciences that the choice of a computational model impacts the research results. In this study of a flood and drought event in the Swiss Thur basin, we ...
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 ...

A least cost transmission planning model considering operation cost
Existing transmission planning models consider basic aspects of the problem. In practice, a transmissionutility needs to model other important details such as operation cost of the power system. In this article, a least ...
Bayesian Analysis for Errors in Variables with Changepoint Models
(UNIV NAC COLOMBIA, DEPT ESTADISTICABOGOTA DC, 2012)
Changepoint regression models have originally been developed in connection with applications in quality control, where a change from the in-control to the out-of-control state has to be detected based on the avaliable ...
