We apply the generalized confidence intervals approach and propose a two-sided tolerance interval for the distribution based on mutually independent statistics , , , …, where is distributed with , hi and ci are known constants, and are independent chi-squared random variables with ni df, for i=1,2,..,q. Some practical examples are given to illustrate the applications of the proposed procedure. A simulation study is conducted to evaluate its frequentist coverage probability. The results indicate that the proposed method may be recommended for use in practical applications. The procedure provided in this paper can be applied to tolerance interval questions arising in arbitrary normal balanced mixed linear model situations.chi-squared approximationgeneralized P-valuesgeneralized confidence intervalslinear modelsvariance components.
