Example Of Kurtosis In Statistics. If excess true default then 3 is subtracted from the result the usual approach so that a normal distribution has kurtosis of zero. 26 12 16 56 112 24.
Excess kurtosis g 2 2 5194 3 0 4806. For another example the 0 5 n 0 1 0 5 n 4 1 distribution is bimodal wavy. Leptokurtic distributions have positive excess kurtosis.
Mesokurtic distributions have excess kurtosis of zero.
Suppose s 2 5 1 3 4 5 0 2. If excess true default then 3 is subtracted from the result the usual approach so that a normal distribution has kurtosis of zero. The kurtosis of a distribution or sample is equal to the 4th central moment divided by the 4th power of the standard deviation minus 3. The formula μ 4 σ 4 3 is the formula for excess kurtosis.
