Class

NumCosmoMathDataDist1d

Description [src]

abstract class NumCosmoMath.DataDist1d : NumCosmoMath.Data
{
  /* No available fields */
}

Abstract class for a sample drawn from a one-dimensional distribution.

The data are NcmDataDist1d:n-points values $x_i$ (NcmDataDist1d:vector), each drawn independently from a distribution with density $p(x)$ given the models in a NcmMSet, and $-2\ln L = \sum_i -2\ln p(x_i)$.

Subclasses implement dist1d_m2lnL_val, which returns $-2\ln p(x)$ for one point, and, to resample, inv_pdf, which maps a uniform number $u \in [0, 1]$ to a draw of the distribution (the inverse of its cumulative distribution). The default methods abort with a message naming the class.

Properties

NumCosmoMath.DataDist1d:n-points

The number of points; changing it reallocates the data and marks it not initialized.

NumCosmoMath.DataDist1d:vector

The sample $x_i$.

Properties inherited from NcmData (5)

NumCosmoMath.Data:bootstrap

The NcmData bootstrap object if any.

NumCosmoMath.Data:desc

Description of the data object.

NumCosmoMath.Data:init

Whether the NcmData is initialized, i.e., holds data.

NumCosmoMath.Data:long-desc

Detailed description of the data object.

NumCosmoMath.Data:name
