Normally distribution
Web14 de jun. de 2024 · If the distribution‘s tails looks like a Pareto distribution α < 2 after we go far enough, we will get an α-stable distribution with the same α. If the left tail and right tail have different α-parameters, the largest one wins and the smallest one dies: we end up with an α-stable distribution that only has a left or right tail (β = ±1).

WebNormal Distribution. The normal distribution is described by the mean ( μ) and the standard deviation ( σ ). The normal distribution is often referred to as a 'bell curve' because of it's shape: It is symmetric, meaning it decreases the same amount on the left and the right of the center.

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.
