Using the least square method, the statistical correlation between C and n is obtained through the numerical value collocation. Then, using Pearson x2 testing method, one of the coefficients n following the rule of distribution in statistics is tested.
然后，采用Pearson x~2分布拟合检验的方法，对n进行非参数假设检验分析，判定其概率分布形式，并根据c和n之间的统计相关式，推得c的概率分布形式。
