normal

sherpa.utils.random.normal(rng: Generator | RandomState | None, loc: float, scale: float, size: Literal[None]) → float

sherpa.utils.random.normal(rng: Generator | RandomState | None, loc: float, scale: float, size: int | Sequence[int] | ndarray) → ndarray

Create a random value from a normal distribution.

Parameters:

• rng (numpy.random.Generator, numpy.random.RandomState, or None) – Determines how the random numbers are created. If set to None then the numpy.random.normal routine is used.

• loc (number, optional) – The location of the normal.

• scale (number, optional) – The scale of the normal.

• size (optional) – The shape and number of elements to create.

Returns:

value

Return type:

number or ndarray
