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 ...
An Efficient Probabilistic Methodology to Evaluate Web Sources as Data Source for Warehousing
Internet is the largest source of data and the requirement of data analytics have fueled the data warehouse to switch from structured conventional Data Warehouse to complex Web Data Warehouse. The dynamic and complex nature ...
Missing data imputation in multivariate data by evolutionary algorithms
(Computers in Human Behavior, 2011-09)
This paper presents a proposal based on an evolutionary algorithm to impute missing observations in multivariate data. A genetic algorithm based on the minimization of an error function derived from their covariance matrix ...
A method to deconvolve stellar rotational velocities II: The probability distribution function via Tikhonov regularization
(EDP Sciences, 2016-11)
Aims. Knowing the distribution of stellar rotational velocities is essential for understanding stellar evolution. Because we measure the projected rotational speed v sin i, we need to solve an ill-posed problem given by a ...
Relaxation of ArH+ by collision with He: Isotopic effects
