%description
For high-dimensional streaming heavy-tailed elliptical data, traditional
sliced inverse regression methods require full offline data and cannot
adapt to incremental data arrival. This package implements Online Sliced
Inverse Regression for Elliptical Model with Streaming Data (OE-SIR)
algorithm with two recursive updating strategies, including offline batch
SIR as benchmark, elliptical heavy-tailed data simulator, subspace
evaluation metric and batch simulation tools for numerical experiments.
