WebA positive kurtosis value indicates we are dealing with a fat tailed distribution, where extreme outcomes are more common than would be predicted by a standard normal … The excess kurtosis is defined as kurtosis minus 3. There are 3 distinct regimes as described below. Distributions with zero excess kurtosis are called mesokurtic, or mesokurtotic. The most prominent example of a mesokurtic distribution is the normal distribution family, regardless of the values of its parameters. A few other well-… certified pre owned all wheel drive car
