Consider a random-effects ANOVA model, Y_{ij}=μ+u_i+ε_{ij}, where the random-effects u_i\sim N(0,σ_a^2) and the random error components ε_{ij}\sim N(0,σ^2). We want to compute CI for the total variance parameter σ_a^2+σ^2. We adopt the generalized pivotal test approach to computing the CI, based on sequentially “calculating" the within-group variance parameter σ^2 and the between-group variance parameter σ_a^2.
