WebbThe skew normal has a number of interesting properties related to alpha: If the skew normal has a skew of zero, then it becomes the normal distribution. If the sign of alpha … WebbKurtosis. In probability theory and statistics, kurtosis (from Greek: κυρτός, kyrtos or kurtos, meaning "curved, arching") is a measure of the "tailedness" of the probability distribution of a real -valued random variable. Like skewness, kurtosis describes a particular aspect of a probability distribution.
