uniform

The Uniform distribution is a continuous distribution bounded on both sides, i.e. the sample lays in the interval [min,max). The probability density does not depend on the value of x. It is a special case of the Beta distribution. It is frequently called rectangular distribution (see Johnson et al).

The Uniform distribution is used to represent a random variable with constant likelihood of being in any small interval between min and max. Note that the probability of max value is 0; the max point never occurs.

Sample 

uniform()

Description

Generates a random value uniformly distributed on the interval [0,1), the upper bound is not included.
