Distributions

fixed

value

Any real number

Draws all values exactly equal to value

uniform

low

Any real number

Draws all values randomly from a uniform distribution with range [low, high]

high

Any real number greater than low

poisson

lam

Any positive real number

Draws all values randomly from a Poisson distribution with rate parameter (mean) lam (lambda)

binomial

size

Any non-negative integer

Draws all values randomly from a binomial distribution with number of trials (n) = size and probability of success on each trial (p) = prob

prob

Any number in [0,1]

lognormal

meanlog

Any real number

Draws all values randomly from a lognormal distribution (natural log, base e) with mean on a log scale of meanlog and standard deviation on a log scale of sdlog

sdlog

Any non-negative real number

truncnorm

mean

Any real number

Draws all values randomly from a truncated normal distribution with mean mean and standard deviation sd, truncated to have a maximum value of a and a minimum value of b

sd

Any non-negative real number

a

Any real number, or -Inf

b

Any real number greater than a, or Inf
