Positive Kurtosis Graph. The solid line shows the normal distribution and the dotted line shows a distribution that has a positive kurtosis value. Kurtosis quantifies whether the tails of the data distribution matches the gaussian distribution.
The kurtosis is positive with a value greater than 3. If z g2 is between 2 and 2 you can t reach any conclusion about the kurtosis. The solid line shows the normal distribution and the dotted line shows a distribution with a positive kurtosis value.
Excess kurtosis might be positive negative or zero.
If z g2 is between 2 and 2 you can t reach any conclusion about the kurtosis. The kurtosis is positive with a value greater than 3. A distribution with fewer values in the tails than a gaussian distribution has a negative kurtosis. This distribution has fatter tails and a sharper peak.
