It is interesting to note that this corner position (Location 7) had the lowest average value but had a large positive skewness
Since the value distributions of available nutrient concentrations are positively skewed, logarithmic transformations (natural logarithm) were applied to the measured values in order to eliminate the positive skewness
of distribution and improve estimation.
The hedge index has a weak standard deviation and a positive skewness
Initial natural logarithmic transformation is applied if required to reduce the positive skewness
and heteroscedasticity of measurements of interest.
In more intuitive terms, positive skewness
means that booms tend to be short and sharp while recessions tend to be long and shallow.
Japan and Italy have estimated |gamma~'s approaching zero and positive skewness
If a variable has positive skewness
, the confidence limits on the variogram are wider than they would otherwise be, and as a result, the variances are less reliable .
Indices' returns display significant positive skewness
where the null hypothesis of skewness coefficients conforming to the normal distribution value of zero is rejected.
With the exception of Bahrain, Israel and Turkey, each MENA country's return series is characterized by positive skewness
, while most developed markets have negative skewness (except for Japan).
The positive skewness
in the Cairo, Casablanca and Amman stock markets returns can be attributed to (a) the recent privatization schemes which were implemented in these financial markets; (b) the extensive sale of government assets to private firms; and (c) the considerable efforts devoted during that period towards enhancing the efficiency, depth, and liquidity of the three stock markets, especially in Egypt and Morocco.
grandiosity and instability) demonstrated positive skewness
and kurtosis; grandiosity demonstrated skewness of 1.
The difference between the right and left tail is not very large, and from the empirical distribution of the return series plotted in Figure 3 we only observe a small positive skewness
