WebThis is the "bell-shaped" curve of the Standard Normal Distribution. It is a Normal Distribution with mean 0 and standard deviation 1. It shows you the percent of population: between 0 and Z (option "0 to Z") less than Z (option "Up to Z") greater than Z (option "Z onwards") It only display values to 0.01%. The Table.

My understanding is that these transforms won't necessarily make the distribution strictly normal -- just more "normal-like". I'm not sure that's what you are going for, particularly because, for example, your Weibull …

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).
All kinds of variables in natural and social sciences are normally or approximately normally distributed. Height, birth weight, reading ability, job satisfaction, or SAT scores are just a few examples of such variables.
