We study two tests for the equality of two population mean vectors under high dimensionality and column-wise dependence by thresholding. They are designed for better power performance when the mean vectors of two populations differ only in sparsely populated coordinates. The first test is...

This thesis concerns the problem of efficient resourceallocation under constraints. In many applications a finitebudget is used and allocating it efficiently can improveperformance. In the context of medical imaging the constraint is exposure to ionizing radiation, e.g., computed tomography...
