We analyzed NFI data using one-way ANOVA and coefficient of skewness. The results indicated that size distributions or population structures of African mahoganies significantly varied within species (P=0.014), among population (P=0.002) and across different forests type (P=0.003).In addition, the...

Essent Group Skewness describes asymmetry of returns from the normal distribution. It can come in the form of negative skewness or positive skewness, depending on whether data points are skewed to the left (negative skew) or to the right (positive skew)

located at a wall-normal locationy/δ≈0.06. The results suggest that Townsends similarity hypothesis for 2Dsurface roughnessis relatively well approximated in the outer region of the flow as reflected by the collapse of the distributions of velocity defect, turbulence intensity, skewness, and flatnes...
The compensation system, employee motivation, and employee satisfaction have received much attention from academics for many years. Existing research, however, does not yet detail the mediation effect of employee motivation on the relationship between th

Coefficient of Variation (CV): The mean absolute deviation value is now changed to CV in the forecast chart’s statistics, where CV is the standard deviation divided by the mean, sometimes used as a proxy for volatility, and useful as a relative measure of risk, in comparing different sized...
This is done by setting a type one error risk As a second aspect of our thesis research, a hierarchical and empirical Bayes methodology was proposed for regionalizing a Pearson type III flood model. The approach is hierarchical in that it assumes homogeneity in terms of skewness coefficient and...
