TruncatedNormal

Truncated normal distribution

Description

The truncated normal (or Gaussian) distribution object defines a normal distribution function with the provided mean, standard_deviation and truncation range (lower_bound and upper_bound) parameters. The probability density function (PDF) of the truncated normal distribution is given by the Eq. (1).

(1)

The parameters and are the mean and standard deviation of the general normal PDF. The and are the general normal PDF and cumulative distribution function (CDF).

Example Input Syntax

The following input file defines a normal distribution with a mean of 100, a standard deviation of 25, and truncation range (50,150).
