Delay

You can either use Distribution property or Expression property as a time source.

Pseudo-random real number generated by an expression that defines a distribution.

normal([stream], u, s)
Normal distribution for mean value u and standard deviation s with an optional stream for seeding a random value to generator.

exponential([stream], lambda)
Exponential distribution where mean value is 1/lambda and variance is 1/lambda^2 with an optional stream for seeding a random value to generator.

gamma([stream], k, theta)
Gamma distribution with shape k and scale theta with an optional stream for seeding a random value to generator.

lognormal([stream], u, s)
Log normal distribution for mean value u and standard deviation s with an optional stream for seeding a random value to generator.

triangular([stream], min, mode, max)
Triangular distribution for given min, mode and max values with an optional stream for seeding a random value to generator.

uniform([stream], a, b)
Uniform distribution in range a <= x < b with an optional stream for seeding a random value to generator.

weibull([stream], k, lambda)
Weibull distribution with shape k and scale lambda with an optional stream for seeding a random value to generator.
