abstract classmethod from_numpy(mkrwt, tafreq, tfreq, ndecn, decn_space, decn_space_lower, decn_space_upper, nobj, obj_wt=None, obj_trans=None, obj_trans_kwargs=None, nineqcv=None, ineqcv_wt=None, ineqcv_trans=None, ineqcv_trans_kwargs=None, neqcv=None, eqcv_wt=None, eqcv_trans=None, eqcv_trans_kwargs=None, **kwargs)

Parameters:

• mkrwt (numpy.ndarray) –

  A marker weight array of shape (p,t).

  Where:

  • p is the number of markers.

  • t is the number of traits.

• tafreq (numpy.ndarray) –

  Taxa allele frequency array of shape (n,p).

  Where:

  • n is the number of taxa.

  • p is the number of markers.

• tfreq (numpy.ndarray) –

  Target allele frequency array of shape (p,t).

  Where:

  • p is the number of markers.

  • t is the number of traits.

Return type:

L1NormGenomicSelectionProblemMixin

property nlatent: Integral

Number of latent variables.
