kinship.BLUP(y, G.train, G.pred=NULL, X=NULL, Z.train=NULL,
K.method="RR", n.profile=10, mixed.method="REML", n.core=1)
``` |

`y` |
Vector ( |

`G.train` |
Matrix ( |

`G.pred` |
Matrix ( |

`X` |
Design matrix ( |

`Z.train` |
0-1 matrix ( |

`K.method` |
"RR" (default) is ridge regression, for which K is the realized additive relationship matrix computed with |

`n.profile` |
For K.method = "GAUSS" or "EXP", the number of points to use in the log-likelihood profile for the scale parameter |

`mixed.method` |
Either "REML" (default) or "ML". |

`n.core` |
Setting n.core > 1 will enable parallel execution of the Gaussian kernel computation (use only at UNIX command line). |

- $g.train
BLUP solution for the training set

- $g.pred
BLUP solution for the prediction set (when G.pred != NULL)

- $beta
ML estimate of fixed effects

For GAUSS or EXP, function also returns

- $profile
log-likelihood profile for the scale parameter
