Detecting the direction of a signal on high-dimensional spheres: Non-null and Le Cam optimality results
Davy Paindaveine, Thomas Verdebout
We consider one of the most important problems in directional statistics, namely the problem of testing the null hypothesis that the spike direction of a Fisher-von Mises-Lange…
Testing for Principal Component Directions under Weak Identifiability
Davy Paindaveine, Julien Remy, Thomas Verdebout
We consider the problem of testing, on the basis of a -variate Gaussian random sample, the null hypothesis against the alternative ${\cal…
Optimal tests for circular reflective symmetry about an unknown central direction
Jose Ameijeiras-Alonso, Christophe Ley, Arthur Pewsey +1
Parametric and semiparametric tests of circular reflective symmetry about an unknown central direction are developed that are locally and asymptotically optimal in the Le Cam sense…
On optimal tests for rotational symmetry against new classes of hyperspherical distributions
Eduardo García-Portugués, Davy Paindaveine, Thomas Verdebout
Motivated by the central role played by rotationally symmetric distributions in directional statistics, we consider the problem of testing rotational symmetry on the hypersphere. W…
