A Graphical Diagnostic Test for Two-Way Contingency Tables
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ciencias - Departamento de Estadística, 2016-01-01)
We propose and illustrate a new graphical method to perform diagnostic analyses in two-way contingency tables. In this method, one observation is added or removed from each cell at a time, whilst the other cells are held ...
PLS regression algorithms in the presence of nonlinearity
(Elsevier Science, 2021-06)
It has long been emphasized that standard PLS regression algorithms like NIPALS and SIMPLS are not suitable for regressions in which there is a nonlinear relationship between the response and the predictors. We show that ...
Graphical diagnostics methods based on generalized residuals for logistic regression models
(2012)
The logistic regression model is remarkably flexible. Nevertheless, lack of fit may also occur so to be able to detect departures from the model is important. In this paper, a generalized empirical probability plot based ...
Statistical Graphics for Survey Weights
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ciencias - Departamento de Estadística, 2014-07-01)
Survey weights are used for correcting known differences between the sample and the population due to sampling design, nonresponse, undercoverage, and other factors. However, practical considerations often result in weights ...
Expert elicitation of the diagnostic performance of two tests for Bacterial Kidney Disease (BKD) surveillance in Atlantic salmon (Salmo salar L.) broodstock in Chile
(2020)
The objective of this study was to obtain diagnostic performance estimates for immunofluorescence antibody test (IFAT) and quantitative polymerase chain reaction (qPCR) tests, for Bacterial Kidney Disease (BKD) surveillance ...
El examen analítico y su importancia clínica. Método de análisis gráfico
(Universidad de La Salle. Ediciones Unisalle, 17 d)
Using concepts of content-based image retrieval to implement graphical testing oracles
(John Wiley & Sons LtdChichester, 2013-05)
Automation of testing is an essential requirement to render it viable for software development. Although there are several testing techniques and criteria in many different domains, developing methods to test programs with ...
Influence diagnostics for linear models with first-order autoregressive elliptical errors
(ELSEVIER SCIENCE BV, 2009)
We introduce in this paper the class of linear models with first-order autoregressive elliptical errors. The score functions and the Fisher information matrices are derived for the parameters of interest and an iterative ...
