---

Method new()

Create a parametrized normal distribution.

Usage

NormalDistribution$new(mu, sigma)

Arguments

mu

Mean of the Normal distribution.

sigma

Standard deviation of the Normal distribution.

Returns

A NormalDistribution object.

---

Method distribution()

Accessor function for the name of the distribution.

Usage

NormalDistribution$distribution()

Returns

Distribution name as character string.

---

Method sample()

Draw a random sample from the model variable.

Usage

NormalDistribution$sample(expected = FALSE)

Arguments

expected

If TRUE, sets the next value retrieved by a call to r() to be the mean of the distribution.

Returns

A sample drawn at random.

---

Method mean()

Return the mean value of the distribution.

Usage

NormalDistribution$mean()

Returns

Expected value as a numeric value.

---

Method SD()

Return the standard deviation of the distribution.

Usage

NormalDistribution$SD()

Returns

Standard deviation as a numeric value

---

Method quantile()

Return the quantiles of the Normal uncertainty distribution.

Usage

NormalDistribution$quantile(probs)

Arguments

probs

Vector of probabilities, in range [0,1].

Returns

Vector of quantiles.

---

Method clone()

The objects of this class are cloneable with this method.

Usage

NormalDistribution$clone(deep = FALSE)

Arguments

deep

Whether to make a deep clone.
