  "Description": "For high-dimensional streaming heavy-tailed elliptical\ndata, traditional sliced inverse regression methods require\nfull offline data and cannot adapt to incremental data arrival.\nThis package implements Online Sliced Inverse Regression for\nElliptical Model with Streaming Data (OSIR) algorithm with two\nrecursive updating strategies, including offline batch SIR as\nbenchmark, elliptical heavy-tailed data simulator, subspace\nevaluation metric and batch simulation tools for numerical\nexperiments.
