Negative Kurtosis Graph. σ is the standard deviation bar x is the mean of the distribution. The solid line shows the normal distribution and the dotted line shows a distribution with a positive kurtosis value.
Kurtosis quantifies whether the tails of the data distribution matches the gaussian distribution. Since this value is negative the curve representing the distribution is skewed to the left i e. Outliers stretch the horizontal axis of the histogram graph which makes the bulk of the data appear in a narrow skinny vertical range thereby giving the skinniness of a leptokurtic distribution.
The solid line shows the normal distribution and the dotted line shows a distribution with a positive kurtosis value.
The solid line shows the normal distribution and the dotted line shows a distribution with a positive kurtosis value. For example data that follow a t distribution have a positive kurtosis value. The solid line shows the normal distribution and the dotted line shows a distribution that has a positive kurtosis value. A distribution with fewer values in the tails than a gaussian distribution has a negative kurtosis.
