ncm_fit_numdiff_m2lnL_lndet_covar (
NcmFit* fit
)
Description [src]
Calculates the logarithm of the determinant of the covariance matrix using the inverse of the Hessian matrix $\partial_i\partial_j -\ln(L)$, where the derivatives are taken with respect to the free parameters.
It sets the covariance matrix in the NcmFitState object associated to the fit
object.
