| 摘 要： | 根据最小一乘回归只考虑偏差绝对值而具有受异常点影响小的特点,将其应用于物价因素对舰船维修工时费用的影响分析中,验证了物价因素对工时费用影响较为显著的结论。通过与最小二乘回归求解该问题进行比较发现,最小一乘方法具有较好的回归效果和稳健性。

| Abstract: | The least absolute deviation regression takes the absolute value of warp only into account, and influenced slightly by the abnormal plot. In this paper, the influence analysis between vessel maintenance cost and price was solved by the least absolute deviation regression, and validated the conclusion that the man-hour cost was influenced by price factor distinctly. It shows that the least absolute deviation regression had better regression effect and robustness, through the question solution by the least squares. |
