text: What does it mean when kurtosis is positive?
text: Platykurtic distributions have negative excess kurtosis.
text: Leptokurtic distributions have positive excess kurtosis.
text: Therefore, for symmetric beta distributions, the excess kurtosis is negative, increasing from a minimum value of −2 at the limit as {α = β} → 0, and approaching a maximum value of zero as {α = β} → ∞.
