“…dea can model different investor preferences and distributional shapes by using several measures of risk and return such as mean, median, standard deviation (Gregoriou et al, 2005a), lower and upper semivariance and semiskewness (Gregoriou et al, 2005b), skewness (Wilkens and Zhu, 2001), excess kurtosis (Nguyen-Thi-Thanh, 2006), time horizons (Galagadera and Silvapulle, 2002), percentage of periods with negative returns, skewness (Wilkens and Zhu, 2001), value at risk, conditional value at risk (Chen and Lin, 2006), downside absolute standard deviation, weighted absolute deviation from quantile, and tail value at risk (Lozano and Gutiérrez, 2008a). Eling (2006) reviews the measures used and concludes there is no single standard choice. Lozano and Gutiérrez (2008a,b) try to account for rational investor behavior using stochastic dominance (Levy, 1992).…”
