In statistics, a normal distribution or Gaussian distribution is a type of continuous probability distribution for a real-valued random variable. The general form of its probability density function is $${\displaystyle f(x)={\frac {1}{\sigma {\sqrt {2\pi }}}}e^{-{\frac {1}{2}}\left({\frac {x-\mu }{\sigma }}\right)^{2}}}$$The … Zobacz więcej Standard normal distribution The simplest case of a normal distribution is known as the standard normal distribution or unit normal distribution.

Witryna8 lip 2016 · 1 Answer Sorted by: 1 Let $W$ be our Gaussian (normal) random variable. Then the cumulative distribution function $F_W (w)$ of $W$ is given by $$F_W (w)=\Pr (W\le w).$$ Note that $F_W (w)$ is the area under the bell-shaped curve from $-\infty$ to $w$. Our normal has mean $0$, so has density function which is symmetric about $0$.
