NumCosmoMathDataFunnel
Description [src]
final class NumCosmoMath.DataFunnel : NumCosmoMath.Data
{
/* No available fields */
}Likelihood of Neal’s funnel distribution.
Evaluates, for the parameters $\nu$ and $x_1, \dots, x_n$ of the NcmModelFunnel
in the NcmMSet, the density of $\nu \sim N(0, 3^2)$, $x_i \mid \nu \sim N(0,
e^{\nu})$ without its constant normalization:
$$-2\ln L = n\nu + (\nu/3)^2 + \sum_i x_i^2 e^{-\nu}.$$
It is a standard test of samplers; its length and degrees of freedom are a nominal 10.
Functions
ncm_data_funnel_clear
If dfu is not NULL, decreases the reference count of dfu by one and sets
*dfu to NULL.
Instance methods
ncm_data_funnel_free
Decreases the reference count of dfu by one. If the reference count reaches
zero, dfu is freed.
