| 摘要: |
| 运用SPSS11.5统计软件包,对广东省新会市双水镇风速随高度变化规律分别作对数曲线、逆曲线、二次曲线、幂函数曲线、S曲线和指数曲线的参数估计。结果表明,在高度<900m的低空下,幂函数的曲线解释量R2最高、标准误差S.E最小,其拟合效果最好。 |

| Abstract: |
| Parametric estimation of logarithmic,inverse,quadratic,power,S,and exponential curves is applied to fit the relations between wind speed and its height in Shuangshui Town by Statistical Package for Social Science 11.5.It indicates that power function is superior in many respects to others,whose curve illumination is the highest and the standard error is the least among these fitting curves. |
