Required parameters

NAME

Set this parameter equal to the name of the probability density function.

TYPE

Set TYPE=UNIFORM to define a uniform probability density function.

Set TYPE=NORMAL to define a normal probability density function.

Set TYPE=LOGNORMAL to define a log-normal probability density function.

Set TYPE=PIECEWISE LINEAR to specify a histogram.

Set TYPE=DISCRETE to specify a discrete probability density function.

Data line to define a uniform probability density function (TYPE=UNIFORM)

First (and only) line

  1. Minimum value of random variable.

  2. Maximum value of random variable.

Data line to define a normal probability density function (TYPE=NORMAL or LOGNORMAL)

First (and only) line

  1. Minimum value of random variable.

  2. Maximum value of random variable.

  3. Mean value of random variable.

  4. Standard deviation of random variable.

Data lines to specify a histogram (TYPE=PIECEWISE LINEAR)

First line

  1. Enter the value of the random variable (midpoint of a range of values for a histogram).

  2. Enter the percentage of the total count that fall in this range of values.

Repeat this data line as often as necessary. Up to eight pairs of entries are allowed per line.

Data line to define a constant probability density function (TYPE=DISCRETE)

First line

  1. Enter a discrete value of the random variable.

  2. Enter the probability of occurrence of this discrete value.

Repeat this data line as often as necessary. Up to eight pairs of entries are allowed per line.
