standard_normal_density/2

Computes the standard normal probability density at the given value.

Compilation flags:

static

Template:

standard_normal_density(Value,Density)

Mode and number of proofs:

standard_normal_density(+number,-float) - one_or_error

Exceptions:

Value is not a number:

type_error(number,Value)

---

standard_normal_distribution/2

Computes an approximation of the standard normal cumulative distribution at the given value.

Compilation flags:

static

Template:

standard_normal_distribution(Value,Probability)

Mode and number of proofs:

standard_normal_distribution(+number,-float) - one_or_error

Exceptions:

Value is not a number:

type_error(number,Value)

---

standard_normal_quantile/2

Computes an approximation of the standard normal quantile for a probability strictly between zero and one.

Compilation flags:

static

Template:

standard_normal_quantile(Probability,Quantile)

Mode and number of proofs:

standard_normal_quantile(+number,-float) - one_or_error

Exceptions:

Probability is not a number:
