Multivariate kurtosis can be problematic by either inflating or deflating standard errors depending on whether the distribution is leptokurtic or platykurtic. |
More descriptively, platykurtic curves tend to be elongated and flat, leptokurtic appear taller and narrow, and mesokurtic curves tend to be bell-shaped like the normal curve. |
Figure 1 Mesokurtic, leptokurtic and platykurtic. |
For instance, regenerative recruitment of adjacent release units might explain the platykurtic sub-population of sparks under some experimental conditions. |
Standard deviation value is 1.344 curve is symmetric and platykurtic. |
Skewness value is approximately 0 thus curve is symmetrical and platykurtic. |
