Distribución normal - Wikipedia, la enciclopedia libre

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 … Prikaži več Standard normal distribution The simplest case of a normal distribution is known as the standard normal distribution or unit normal distribution. This is a special case when Prikaži več Central limit theorem The central limit theorem states that under certain (fairly common) conditions, the sum of many random variables will have an approximately … Prikaži več The occurrence of normal distribution in practical problems can be loosely classified into four categories: 1. Exactly normal distributions; 2. Approximately normal laws, for example when such approximation is justified by the Prikaži več Development Some authors attribute the credit for the discovery of the normal distribution to de Moivre, who in 1738 published in the second edition of … Prikaži več The normal distribution is the only distribution whose cumulants beyond the first two (i.e., other than the mean and variance) … Prikaži več Estimation of parameters It is often the case that we do not know the parameters of the normal distribution, but instead want to estimate them. That is, having a sample Prikaži več Generating values from normal distribution In computer simulations, especially in applications of the Monte-Carlo method, it is often desirable to generate values that are normally distributed. The algorithms listed below all … Prikaži več SpletThe generalized normal distribution or generalized Gaussian distribution (GGD) is either of two families of parametric continuous probability distributions on the real line. Both families add a shape parameter to the normal distribution.To distinguish the two families, they are referred to below as "symmetric" and "asymmetric"; however, this is not a standard … 外国人材受け入れ拡充策
