Single-stage sampling procedure for heteroscedasticity in multiple comparisons with a control. (English) Zbl 07872075
Summary: Given \(k (\geq 2)\) independent and normally distributed populations with unknown means and unknown (and possibly unequal) variances, we used the single-stage sampling procedure for multiple comparison with a control to the problem of unequal sample sizes. A simulation of the family-wise error type I was conducted to validate the quality of the procedure and a numerical example was provided for illustrating this procedure. We provided a user-friendly interface by \(R\) shiny to obtain the critical values for the practitioners.
