WebA set of data with a high kurtosis value will produce a distribution curve with a higher peak value at the mean and longer tails, or, in other words, more data points at the extreme values from the mean. Compare the distributions shown for a kurtosis value of 7 with the traditional Gaussian distribution – kurtosis value of 3 (Figure 1).

WebThe higher kurtosis values include the higher peak accelerations, which are responsible for a more damaging test and shorter testing time. Kurtosis control proves to be a great improvement on traditional random vibration from every perspective. Figure 2.12. Kurtosis comparison of lightbulb failure tests. Figure 2.13. WebSep 17, 2015 · The accuracy of the variance estimate depends strongly on kurtosis. The reason this happens is that with high kurtosis, the distribution allows rare, extreme potentially observable data. Thus the data-generating process will produce very extreme values in some samples, and not so extreme values in others. WebNov 9, 2024 · A high kurtosis distribution has a sharper peak and longer fatter tails, while a low kurtosis distribution has a more rounded pean and shorter thinner tails.
