HL.mean {asbio} | R Documentation |
Calculates the Hodges-Lehman estimate of location –which is consistent for the true pseudomedian– using Walsh averages (Hollander and Wolfe 1999, pgs. 51-55). If requested, the function also provides confidence intervals for the true pseudomedian. In a symmetric distribution the mean, median, and pseudomedian will be identical.
