The accursed part of your [[probability]] distribution, where you discover it diverges from the [[normal distribution]] lazily factored into all your models.


In probability theory, “kurtosis” (from Greek: κυρτός, meaning “curved”) is the measure of the fatness of the tails of a distribution of variables. Higher kurtosis corresponds to greater deviation from the [[mean]] — more [[outlier]]s — and is less interested in the shape of the distribution close to the mean.
