Several methods of curve-fitting data yield consistent estimates of parameter values . 几种曲线似合数据的方法均能得到参数值的一致性估计。
The tradition hydrology frequency computation method is supposed that the universe is following the p - iii distribution . using the method of curve - fitting to estimate parameters according samples , and then get the design value 我们传统的水文频率计算方法一般都是假定总体服从p -型分布,然后采用适线法根据样本估计参数,进而推求设计值。
