Image summary
Natural logarithm of the probability density of the Pearson type VII distribution
The red curve shows the limiting density with infinite kurtosis; the blue curve shows the density with kurtosis equal to 2; the black curve shows the limiting (normal) density with zero kurtosis. The gray curves (between the blue and the black) show densities with kurtoses 1, 1/2, 1/4, 1/8, and 1/16.
