WebThat is, if the complementary cumulative distribution of a random variable X can be expressed as [citation needed] [>], >then the distribution is said to have a fat tail if <.For such values the variance and the skewness of the tail are mathematically undefined (a special property of the power-law distribution), and hence larger than any normal or … Web20 de mai. de 2024 · In some cases, this can be corrected by transforming the data via calculating the square root of the observations. Alternately, the distribution may be exponential, but may look normal if the observations are transformed by taking the natural logarithm of the values. Data with this distribution is called log-normal.
