Agreement coefficients for continuous variables: A review
Ronny Vallejos
Agreement coefficients provide a fundamental framework for quantifying the concordance between two or more measurement methods applied to the same continuous variable. Unlike corre…
Optimized imaging prefiltering for enhanced image segmentation
Ronny Vallejos, Felipe Osorio, Sebastian Vidal +1
The Box-Cox transformation, introduced in 1964, is a widely used statistical tool for stabilizing variance and improving normality in data analysis. Its application in image proces…
Comparing two spatial variables with the probability of agreement
Jonathan Acosta, Ronny Vallejos, Aaron M. Ellison +2
Computing the agreement between two continuous sequences is of great interest in statistics when comparing two instruments or one instrument with a gold standard. The probability o…
A Spatial Concordance Correlation Coefficient with an Application to Image Analysis
Ronny Vallejos, Javier Pérez, Aaron M. Ellison +1
In this work we define a spatial concordance coefficient for second-order stationary processes. This problem has been widely addressed in a non-spatial context, but here we conside…
Sensitivity of codispersion to noise and error in ecological and environmental data
Ronny Vallejos, Hannah L Buckley, Bradley S Case +2
Codispersion analysis is a new statistical method developed to assess spatial covariation between two spatial processes that may not be isotropic or stationary. Its application to…
SpatialPack: Computing the Association Between Two Spatial Processes
Felipe Osorio, Ronny Vallejos, Francisco Cuevas
An R package SpatialPack that implements routines to compute point estimators and perform hypothesis testing of the spatial association between two stochastic sequences is introduc…
