Mode testing, critical bandwidth and excess mass
Jose Ameijeiras-Alonso, Rosa M. Crujeiras, Alberto Rodríguez-Casal
The identification of peaks or maxima in probability densities, by mode testing or bump hunting, has become an important problem in applied fields. This task has been approached in…
CircSiZer: an exploratory tool for circular data
María Oliveira, Rosa M. Crujeiras, Alberto Rodríguez-Casal
Smoothing methods and SiZer (SIgnificant ZERo crossing of the derivatives) are useful tools for exploring significant underlying structures in data samples. An extension of SiZer t…
A plug-in rule for bandwidth selection in circular density estimation
M. Oliveira, R. M. Crujeiras, A. Rodríguez-Casal
A new plug-in rule procedure for bandwidth selection in kernel circular density estimation is introduced. The performance of this proposal is checked throughout a simulation study…
Recovering the shape of a point cloud in the plane
Beatriz Pateiro-López, Alberto Rodríguez Casal
In this work we deal with the problem of support estimation under shape restrictions. The shape restriction we deal with is an extension of the notion of convexity named alpha-conv…
