一种新的信度估计

A New Estimation of Reliability Coefficient

应用相关系数的信息并结合重排不等式 ,引入了一个新的信度系数 ζ ,并证明了 ζ≥α且在某些情况下 ,ζ可以弥补α系数、β系数及γ系数的不足 ,有时 ζ比λ2

By using the information of correlation coefficient and combined rearrangement inequality, a new estimation of reliability coefficient ζ is derived. It is shown that ζ≥αand that ζ could be used to mend a drawback of coefficients α,β,γ in some cases and sometimes it is better than λ 2.
