Principal Points of Symmetric, Strongly Unimodal DistributionsStatistics and Probability Letters
AbstractExamples illustrate that splitting a symmetric, unimodal distribution into two groups so as to minimize the sum of the within-group variances does not always occur at the mean. Strong unimodality is shown to be a sufficient condition for the optimal cutpoint to occur at the mean.
