Method
NumCosmoMathFitfisher_bias
Declaration [src]
NcmVector*
ncm_fit_fisher_bias (
NcmFit* fit,
NcmVector* f_true
)
Description [src]
Calculates the covariance from the Fisher matrix and the bias vector, see
ncm_dataset_fisher_matrix_bias(). The bias vector is calculated using the
the theory vector f_true as the true model expectation values.
Note that this function does not use the gradient defined in the fit object, it
always uses the accurate numerical differentiation methods implemented in the
NcmDiff object.
It sets the covariance matrix in the NcmFitState object associated to the
fit object. Moreover, it computes the final bias vector, that is, the inverse
of the Fisher matrix times the bias vector returns it.
Parameters
f_true-
Type:
NcmVectorA
NcmVector.The data is owned by the caller of the method.
Return value
Type: NcmVector
The bias vector.
| The caller of the method takes ownership of the returned data, and is responsible for freeing it. |
