The decline in kurtosis for the other classes is much weaker, and is generated by the same processes that produce negative skew. Normality of the residuals is rejected because of the considerable excess kurtosis. The plotted fourth-order approximation has a mean, variance, skewness, and kurtosis that are equal to the values in the simulated economy. Skewness and kurtosis, on the other hand, which are statistical indicators measuring concentration and asymmetry of the distribution, reach their maximum. The kurtosis statistics, on its part, signals that the distribution is significantly leptokurtic. Distributions for maternal and paternal anger had modal values of zero, with significant positive skewness and kurtosis for paternal anger. The computation of the kurtosis is, then, straightforward using the previous two results. Following these transformations, all univariate skewness and kurtosis statistics were within reasonable limits. The kurtosis in the distributions of shocks needs to be modeled accurately. As can be seen, the resulting distribution is characterized by significant excess kurtosis and slight positive skewness. Changes in the variance, skew and kurtosis of the distribution of genotypic values are compared with those found or expected in previous models. But he also found the indicated kurtosis of line (b) is 1400. This agrees well with the behaviour of the skewness and the kurtosis shown in figure 7. This guarantees that directional selection will produce skew and positive kurtosis proportional to the peakshift, given the restrictions on mutational effects. This kurtosis should make some of the other moments a little suspicious. No skew or kurtosis was detected in any of the traits at other densities. Accordingly, the data for each year were transformed using log10 to reduce skew and kurtosis. |
