In this paper, we construct a nonparametric regression quantile estimator by using the local linear fitting for left-truncated data, and establish the Bahadur-type representation and asymptotic normality of the proposed estimator when the observations form a stationary α-mixing sequence....

In this paper, we construct a local linear composite quantile regression (CQR) estimator of regression function for left-truncated data, which extends the CQR method to the left-truncated model. The asymptotic normality of the proposed estimator is also established. The estimator is much more...

The government has been acting as an important role in the formation and operation of closed-loop supply chain. This paper focuses on how consumption-subsidy influences dual-channel closed-loop supply chain. After introducing government consumption-subsidy program and dual-channel closed-loop...
