def_dist {ern}

Define a family of distributions.

Description

Define a family of distributions.

Usage

def_dist(dist, ...)

Arguments

dist

distribution type. Distributions currently supported are:

• norm = normal,

• lnorm = log-normal,

• gamma = Gamma,

• unif = uniform

...

a series of distribution parameters. Included should be the following:

• mean distribution mean (only for dist = lnorm or gamma).

• mean_sd standard deviation of the mean (only for dist = lnorm or gamma).

• sd standard deviation (only for dist = lnorm or gamma).

• sd_sd standard deviation of the standard deviation (only for dist = lnorm or gamma).

• min minimum value of the random variable modelled by this distribution (only for dist = unif).

• max maximum value of the random variable modelled by this distribution.

Value

List with components specified in the parameters.

Examples

d = def_dist(
  dist     = "gamma",
  mean     = 3.49,
  mean_sd  = 0.1477,
  shape    = 8.5,
  shape_sd = 1.8945,
  max      = 8
)
print(d)
