Abstract
Throughout the book we have stressed several properties that distinguish between the GMD and the variance, claiming that those properties give an advantage to using the GMD over the variance, in cases where the assumption of normality is not supported by the data. Among those properties are the following:

These are assumptions of convenience; the conclusions reached here are not affected by allowing a “guessing parameter” to affect the item response function (see Lord, 1980, p. 12).

This section is based on Yitzhaki, Itzhaki and Pudalov, (2011).

See, for example, Wodon and Yitzhaki (2006) for a critique of the β convergence concept used in macro-economics in order to prove convergence in the growth rates of countries. Wodon and Yitzhaki found that this concept may lead both to convergence when moving forward and backward in time, which leads to a contradiction. See also O’Neill and Van Kerm (2008).
