WebBased on the new correlation, we further propose a robust model-free feature screening procedure for ultrahigh dimensional data and establish its sure screening property and rank consistency property without imposing the subexponential or sub-Gaussian tail condition, which is commonly required in the literature of feature screening.

Webthat sure screening can be achieved without resorting to a particular form of model for the data. Moreover, we advocate the use of model-free screening methods in practice. The reasons are twofold. First, the model-free screening results are much more robust in the sense that the sure screening property can hold under much weaker conditions.
