Class

NumCosmoMathMSetTransKern

Description [src] 

abstract class NumCosmoMath.MSetTransKern : GObject.Object
{
  /* No available fields */
}

Abstract Class for a transition kernel and prior.

This object defines the abstract class for a transition kernel and prior. It serves as the base class for all transition kernels and priors, with two main purposes:

  • To define the interface for all transition kernels for use in the NcmFitMCMC object.
  • To define the interface for all priors, generating random parameter vectors with multivariate parameters.

Notably, it acts as a prior sampler for NcmFitESMCMC, generating the initial population’s first set of random parameter vectors.

Functions

ncm_mset_trans_kern_clear

If tkern is not NULL, unrefs it and sets tkern to NULL.

Instance methods

ncm_mset_trans_kern_free

Increases the reference count of tkern.

ncm_mset_trans_kern_generate

Generates a new point thetastar from theta using the transition kernel.

ncm_mset_trans_kern_get_name
No description available.

ncm_mset_trans_kern_pdf

Computes the value of the kernel at (theta, thetastar).

ncm_mset_trans_kern_peek_mset
No description available.

ncm_mset_trans_kern_prior_pdf

Computes the value of the kernel at (ktern->theta, thetastar). To use as a prior one must call the ncm_mset_trans_kern_set_prior() or ncm_mset_trans_kern_set_prior_from_mset() first.

ncm_mset_trans_kern_prior_sample

Sample from the transition kernel using it as a prior. To use as a prior one must call one of the functions ncm_mset_trans_kern_set_prior_* first.

ncm_mset_trans_kern_ref

Increases the reference count of tkern.

ncm_mset_trans_kern_reset

Resets the transition kernel.

ncm_mset_trans_kern_set_mset

Sets the mset as the internal set NcmMSet to be used by the transition kernel.

ncm_mset_trans_kern_set_prior

Sets the theta as the prior mean. This allows the transition kernel to be used as a prior sampler.

ncm_mset_trans_kern_set_prior_from_mset

As ncm_mset_trans_kern_set_prior() but uses the values present in the internal set NcmMSet.
