Kurtosis Formula In Statistics. The greater the value of beta 2 the more peaked or leptokurtic the curve. Mesokurtic distributions have excess kurtosis of zero.
The formula μ 4 σ 4 3 is the formula for excess kurtosis. The greater the value of beta 2 the more peaked or leptokurtic the curve. The variance of the sample kurtosis of a sample of size n from the normal distribution is.
Mesokurtic distributions have excess kurtosis of zero.
Platykurtic distributions have negative excess kurtosis. μ4 x ˉx 4 n. β2 μ4 μ2. The skewness can be calculated from the following formula.
