Help Center Help Center. A NormalDistribution object consists of parameters, a model description, and sample data for a normal probability distribution. The normal distribution, sometimes called the Gaussian distribution, is a two-parameter family of curves. The usual justification for using the normal distribution for modeling is the Central Limit theorem, which states roughly that the sum of independent samples from any distribution with finite mean and variance converges to the normal distribution as the sample size goes to infinity. There are several ways to create a NormalDistribution probability distribution object.

Help Center Help Center. Create a probability distribution object NormalDistribution by fitting a probability distribution to sample data or by specifying parameter values. Then, use object functions to evaluate the distribution, generate random numbers, and so on. Work with the normal distribution interactively by using the Distribution Fitter app. You can export an object from the app and use the object functions. Use distribution-specific functions with specified distribution parameters. The distribution-specific functions can accept parameters of multiple normal distributions. Use generic distribution functions cdf , icdf , pdf , random with a specified distribution name 'Normal' and parameters. To learn about the normal distribution, see Normal Distribution. Learn about the normal distribution. The normal distribution is a two-parameter mean and standard deviation family of curves. Central Limit Theorem states that the normal distribution models the sum of independent samples from any distribution as the sample size goes to infinity.

Probability Distribution Function.

A normal distribution does not have limits. In theory it is possible to see generated points that lie all the way out to infinity, or at least arbitrarily close to that point. You might consider a truncated normal distribution. You can do the search as easily as can I. A truncated normal distribution is not that difficult to sample from either. The stats toolbox would make it fairly easy. Just as easy is to make use of the central limit theorem.
