Kurtosis

Kurtosis[list]
gives the coefficient of kurtosis for the elements in list.
Kurtosis[dist]
gives the coefficient of kurtosis for the symbolic distribution dist.
  • Kurtosis measures the concentration of data around the peak and in the tails versus the concentration in the flanks.
  • A kurtosis larger than 3 indicates a distribution that is more peaked and has heavier tails than a normal distribution with the same variance. A kurtosis smaller than 3 indicates a distribution that is flatter.
  • Kurtosis handles both numerical and symbolic data.
  • Kurtosis[{{x1, y1, ...}, {x2, y2, ...}, ...}] gives {Kurtosis[{x1, x2, ...}], Kurtosis[{y1, y2, ...}], ...}.
