The letter index of skewness (l.c.s.) is built by fitting the standardized sample midsummaries with a least squares straight line, while the letter index of kurtosis (l.c.k.) is obtained by fitting the pseudosigmas (after a simple transformation), in the same way. A robust modification of the above defined indices is proposed. Finally, an application to a set of geographical data is given, with some comments about the effect of outliers.}, number={2}, journal={Statistica}, author={Brizzi, Maurizio}, year={2000}, month={Jan.}, pages={243–258} }
