athena.subspaces.Subspaces._bootstrap_replicate

static Subspaces._bootstrap_replicate(matrix, weights)[source]

Return a bootstrap replicate.

A bootstrap replicate is a sampling-with-replacement strategy from a given data set.

Parameters
  • matrix (numpy.ndarray) – matrix from which will be sampled N rows. N corresponds to the number of rows of weights.

  • weights (numpy.ndarray) – n_samples-by-1 weight vector, corresponds to numerical quadrature rule used to estimate matrix whose eigenspaces define the active subspace.
