# Computes the univariate MCD estimator of scatter

### Description

Pseudo Stahel Donoho Outlyingness based estimates of PCA.

### Usage

1 |

### Arguments

`z0` |
Either a data matrix or the result of a call to |

`h` |
Number of observation used to compute the univairate outlyingness. Defaults to |

`seed` |
Seed used to initialize the RNG. Defaults to 1. |

`q` |
Number of components. Defaults to |

`ndir` |
Number of projection used to compute the PP outlyngness. |

### Value

A list with components:

`rawDist:` |
Outlyingness index of the data on the raw q-dimensonal subset that initialized H*. |

`best:` |
the indexes of the members of the H+, the FastHSC subset after the C-steps. |

`center:` |
the p-vector of column means of the observations with indexes in |

`loadings:` |
the (rank q) loadings matrix of the observations with indexes in |

`eigenvalues:` |
the first |
