about high-dimensional regression data I am doing experiments on the high-dimensional regression. However, it is hard to obtain the practical or synthetic high-dimensional data. I have checked on UCI website as well as some papers with related to this topic. Currently, I have not obtained satisfactory datasets. 

Could someone give me some hints on how to search and obtain the high-dimensional data? Thanks in advance.
