Random Walk Standard Deviation¶

class pypomp.core.rw_sigma.RWSigma(sigmas: dict[str, float], init_names: list[str] = [])[source]¶

Represents the random walk standard deviation for the parameters of a model used in the Iterated Filtering 2 (IF2) algorithm.

Attributes

`sigmas`	Dictionary mapping parameter names to sigma values.
`init_names`	List of parameter names that are considered initial parameters.
`not_init_names`	List of parameter names that are not considered initial parameters.
`all_names`	List of all parameter names.

Methods

cool(factor)

Reduces all sigmas by multiplying them by the specified factor in place.
