Returns a bootstrap aggregation of CART-histograms or greedy histograms.

1 2 3 |

`dendat` |
n*d data matrix |

`B` |
positive integer; the number of aggregated histograms |

`leaf` |
the cardinality of the partitions of the aggregated histograms |

`minobs` |
non-negative integer; a property of aggregated histograms; splitting of a bin will be continued if the bin containes "minobs" or more observations |

`seed` |
the seed for the random number generation of the random selection of the bootstrap sample |

`sample` |
"bagg" or "worpl"; the bootstrapping method; "worpl" for the n/2-out-of-n without replacement; "bagg" for n-out-of-n with replacement |

`prune` |
"on" or "off"; if "on", then CART-histograms will be aggregated; if "off", then greedy histograms will be aggregated |

`splitscan` |
internal (how many splits will be used for random split selection) |

`seedf` |
internal (seed for random split selection) |

`scatter` |
internal (random perturbation of observations) |

`src` |
internal ("c" or "R" code) |

`method` |
"loglik" or "projec"; the empirical risk is either the log-likelihood or the L2 empirical risk |
