kurtosi
Kurtosis is a statistical measure that describes the shape of a probability distribution, specifically the "tailedness" of the distribution relative to a normal distribution. It provides insight into the extent of outliers and the peakedness of a dataset compared to a Gaussian (bell-shaped) curve. The term originates from the Greek word *kurtos*, meaning "curved" or "rounded."
In probability theory and statistics, kurtosis is formally defined as the fourth standardized moment of a random
Kurtosis is particularly useful in finance, where asset returns often exhibit fat tails, meaning extreme events
There are two primary types of kurtosis: *excess kurtosis* and *Fisher’s kurtosis*. Excess kurtosis is more commonly
While kurtosis is valuable for understanding distribution shape, it should be used alongside other descriptive statistics
