Method

NumCosmoMathMSetCatalogcalc_ci_direct

Declaration [src]

NcmMatrix*
ncm_mset_catalog_calc_ci_direct (
  NcmMSetCatalog* mcat,
  NcmMSetFunc* func,
  NcmVector* x_v,
  GArray* p_val
)

Description [src]

Calculates the mean and the confidence interval (CI) for the value of func for each p-value in p_val. It stores the results in a NcmVector, where the first element contains the mean and the following contain the lower and upper bounds for each p-value in p_val.

This function calculates the quantile directly using: gsl_stats_quantile_from_sorted_data for this reason it must allocates the catalog size times the number of elements in x, for a less memory intensive version use ncm_mset_catalog_calc_ci_interp().

The NcmMSetFunc func must be of dimension one.

Example:

If p_val contains two values ($1\sigma$) 0.6827 and ($\sigma$) 0.9545, the first element will contain the mean, the second and third, the lower and upper bounds, respectively. Then, the fourth and fifth elements the lower and upper bounds of $2\sigma$ CI.

Parameters

func

Type: NcmMSetFunc

A NcmMSetFunc of type n-n.

The data is owned by the caller of the method.

x_v

Type: NcmVector

NcmVector of arguments of func.

The data is owned by the caller of the method.

p_val

Type: An array of double

P-values for the confidence intervals.

The data is owned by the caller of the method.

Return value

Type: NcmMatrix

A NcmVector containing the mean and lower/upper bound of the confidence interval for func.

The caller of the method takes ownership of the returned data, and is responsible for freeing it.
