| مستخلص: |
The pseudo-median procedure is a technique for treatment group comparison which adopts the pseudo-median as a location parameter. The power of this procedure is estimated in various shapes of distributions and different degrees of variation. The bootstrap method is employed to generate the approximate sampling distribution of the statistic. The results show that the power of this procedure is not affected by the shape of the data. However, the power is affected somewhat by the heterogeneity of variances. [ABSTRACT FROM AUTHOR] |
