Web27 de jun. de 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 … WebOn the other hand, if most observations were tightly clustered in the middle and a fairly small fraction of observations were very far from the many observations in the middle, then …
