Webb23 apr. 2024 · From the general formula for the moments, we can also compute the skewness and kurtosis of the lognormal distribution. The skewness and kurtosis of X are skew(X) = (eσ2 + 2)√eσ2 − 1 kurt(X) = e4σ2 + 2e3σ2 + 3e2σ2 − 3 Proof The fact that the skewness and kurtosis do not depend on μ is due to the fact that μ is a scale parameter.
