Testing Whether Independent Treatment Groups Have Equal Medians.

Wilcox, Rand R.

Psychometrika, v56 n3 p381-95 Sep 1991

New methods for comparing the medians corresponding to independent treatment groups are suggested. Procedures are based on the estimator of F. Harrell and C. Davis in conjunction with a modification and extension of the bootstrap calibration technique suggested by W. Loh. Data from two groups provide an illustration. (SLD)
