Learn how the coefficient of variation (CV) helps individuals compare the risk and return for multiple investments.

The problem of estimating the coefficient of variation is considered when it is a priori suspected that two coefficients of variations are the same. It is advantageous to pool the data for making ...

This article presents an analysis of the small-sample distribution of a class of approximate pivotal quantities for a normal coefficient of variation that contains the approximations of McKay, David, ...
