| Several standard summary statistics are also examined, namely volatility, skewness, and kurtosis. |
| Results indicate that the skewness and the kurtosis of term premiums differ statistically from that of a normally distributed time series. |
| Values of 2 standard errors of kurtosis or more probably differ from mesokurtic to a significant degree. |
| The volatility measure is fairly robust across methods, while the skewness and kurtosis measure are model-sensitive. |
| Skewness was not detected in these distributions, but kurtosis was in two of them. |
| The kurtosis of the movement distributions was also estimated for each species. |
