| Abstract: |
| In this paper,the author studies the Marcinkiewicz-Zygmund inequality for pairwise negative quadrant dependent (NQD) random variables and it applications.By using the truncated method,the author obtains the Marcinkiewicz-Zygmund inequality with exponent p(1 ≤ p < 2) for pairwise NQD random variables.As applications,the author obtains the simpler proofs of two Lr convergence results for pairwise NQD random variables,which improve the corresponding work by Chen [10] and Sung [20] respectively. |
