Method
NumCosmoMathStatsDistpeek_center_shrink_matrix
Declaration [src]
NcmMatrix*
ncm_stats_dist_peek_center_shrink_matrix (
NcmStatsDist* sd
)
Description [src]
Gets the $d \times d$ center shrinkage transform $A$ applied in the last
preparation: the centers are $c_i = \mu + A (x_i - \mu)$ and the kernel scale
matrices $\hat A \Sigma_i \hat A^T$ with $\hat A = A / a$, see the class
description. It is the identity when center shrinkage is disabled, and NULL before
the first preparation.
Return value
Type: NcmMatrix
The transform $A$.

The return value can be NULL. |
