耐抗稳健的Ⅲ型乘法频率曲线——原理与方法

The Resistant and Robust Multiplication Frequency Curve TypeⅢ —— The Principle and Methodology

基于概率乘法定理和中位数,提出了Ⅲ型乘法频率曲线的原理、方法。P(K≥k)=1-0.5^D,D=(a-1)/(a^k^c)-1),0.5是中位数频率。用密度参数a、c直接配线的方法非常简易。是一种耐抗和稳健的线型和方法。

Based on the multiplication theorem and median,the principle and methodology of mul - tiplication frequency curve typeⅢhas been presented.For example,P(K≥k)=1-0.5^D,D=(a-1)/(a^(k^c)-1),0.5is the frequency of median.The curve fitting by means of the density paramet - ers a and c is quite simple and easy.The frequency curve and the method are resistant and ro - bust.
