摘要:

Recently, large scale datasets appear frequently due to the development of techniques. Distributed computation has attracted attentions from statistician. Since quantile regression has been an effective alternative to the classic mean regression in many fields. However, computationally efficient quantile regression estimates for large scale datasets are less developed. In this paper, we consider the penalized quantile regression estimate obtained via a new efficient ADMM algorithm that could be implemented in a distributed manner, which has been shown to be able to carry out variable selection for massive data.
