This paper proposes a novel shrinkage estimator for high-dimensional covariance matrices by extending the Oracle Approximating Shrinkage (OAS) of Chen et al. (2009) to target the diagonal elements of ...

About This MPI program processes a matrix in parallel. Processor 0 gets user input, broadcasts size, and scatters data (MPI_Scatter). It checks strict diagonal dominance, finds max absolute diagonal ...
