Skewness - Overview, Types, How to Measure and Interpret

WebIn probability theory and statistics, skewness is a measure of the asymmetry of the probability distribution of a real-valued random variable about its mean. The skewness value can be positive, zero, negative, or undefined. For a unimodal distribution, negative skew commonly indicates that the tail is on the left side of the distribution, and positive skew … WebThe term “Kurtosis” refers to the statistical measure that describes the shape of either tail of a distribution, i.e. whether the distribution is heavy-tailed (presence of outliers) or light-tailed (paucity of outliers) compared … lbhf summer in the cityWebA fat-tailed distribution is a probability distribution that exhibits a large skewness or kurtosis, relative to that of either a normal distribution or an exponential distribution.

The closer the number is to zero, the fatter the tails. The closer the number is to 1 (it can never exceed 1!), the thinner the tails. For example, the normal distribution has a MAD/SD ratio of 0.7970, which happens to be the square root of 2 over pi (not a coincidence, try ...
