New statistical test for Gaussian random fields introduced

Researchers have introduced a novel statistical concept called the "second maximum" of a Gaussian random field on a Riemannian manifold. This statistic, defined as the largest value of the field away from its global maximum after accounting for the field's value and gradient at that point, helps characterize the distribution of the global maximum. The work also presents an exact spacing test derived from this concept, applicable to various scenarios including Gaussian symmetric tensors, continuous sparse deconvolution, and neural networks. Additionally, a Studentized version, the t-spacing test, is developed for situations where the variance-covariance function is only known up to a scaling factor. AI
