A new two-stage multiple comparison procedure for comparing several exponential populations with a control under heteroscedasticity

Sample Size Determination for Two-Stage Multiple Comparisons for Exponential Location Parameters with the Average

“…), which are different from the one given in Theorem 1 so that the design constant in Maurya et al [10] is different from ours.…”

“…Using these values, we yield ϕ(m, P * , γ) = 1 h t +g γ = 1 3.1273+ 3.1273 = 0.1599 and then the design constant is determined as c = δϕ(m, P * , γ) = 0.3(0.1599) = 0.04797. The values of h t and g γ in Maurya et al [10] are…”

“…Unlike a one-stage procedure, a two-stage procedure is design-oriented. Maurya et al [10] modified the procedure proposed by Lam and Ng [9] to get a new procedure with smaller confidence width. They also discussed the criteria to find the design constant required for the correct detection for the given deviation of k location parameters from the control.…”
