Web27 Jun 2024 · Revised on November 10, 2024. Kurtosis is a measure of the tailedness of a distribution. Tailedness is how often outliers occur. Excess kurtosis is the tailedness of a distribution relative to a normal distribution. Distributions with medium kurtosis (medium tails) are mesokurtic. Distributions with low kurtosis (thin tails) are platykurtic. WebA long tail distribution has tails that taper off gradually rather than drop off sharply.
