A note on the multiple comparisons of exponential location parameters with several controls under heteroscedasticity

Several researchers have addressed the problem of constructing simultaneous confidence intervals insert ignore into journalissuearticles values(SCIs); for comparing exponential location parameters with a control or controls under heteroscedasticity when sample sizes are equal or unequal. They usually used simulation-based inference procedures or Lam`s technique that leads to conservative SCIs. In this paper, we present a set of SCIs for comparing exponential location parameters with a control, controls and the best control under heteroscedasticity when sample sizes are possibly unequal. Our method is not a simulation-based inference procedure and our results show that the proposed SCIs have some advantages over others.
