One is not objectively “better” than the other. You can put $10,000 into a negative-skew strategy and another $10,000 in a positive-skew strategy and end up with $15,000 from both because the skewness of each strategy doesn’t speak to itsreturnover time. Instead, skewness speaks to...
What is the difference between positive skew versus negative skew? Skewness is the measurement of a a coefficient that has the ability to be positive, negative or neutral (zero). The coefficient of the skew is the measurement of the magnitude of the symmetry in the distribution of outcomes of...
The model is tested in convective (positively skewed) and canopy (negatively skewed) turbulence. The mean and fluctuations of the concentration field in canopy turbulence are compared to experimental data showing the important improvements determined by the inclusion of the skewness effects close to ...

In the boxplot, the relationship between quartiles for a negative skewness is given by: Similar to what we did earlier, if Q3-Q2 and Q2-Q1 are equal, then we look for the length of whiskers. And if the length of the left whisker is greater than that of the right whisker, then we...
