摘要
在算出Γ分布的离差系数CV、偏度系数CS以及峰度系数CE的基础上,建立了这三个系数之间关系式:(1)CS=2CV;(2)CE=3+6CV2;(3)2CE=6+3CS2;(4)CE=3+3CVCS.并作了详细证明.
On the base of figuring out Γ distribution deviation coefficient CV,coefficient CS as well as in the peak coefficient CE foundation,the author presente the relationships between these three coefficients: (1) CS=2CV; (2) CE=3+6CV; (3) 2CE=6+3CS2; (4) CE=3+3CVCS. And the proof of them has been made in detail.
