An almost unbiased estimator of the coefficient of variation

Research output: Contribution to journal › Article

Abstract

A bias correction method for inequality measures is proposed. The coefficient of variation squared (CV2) is used as an example and its sampling properties, bias, and mean squared error are provided. CV2 is shown to be downward biased for positively skewed distributions. A bias corrected estimator is provided.
