An algorithm for multiple change point analysis that uses dynamic programming and pruning. The E-statistic is used as the goodness-of-fit measure.

1 |

`Z` |
A T x d matrix containing the length T time series with d-dimensional observations. |

`K` |
The maximum number of change points. |

`minsize` |
The minimum segment size. |

`alpha` |
The moment index used for determining the distance between and within segments. |

`verbose` |
A flag indicating if status updates should be printed. |

Segmentations are found through the use of dynamic programming and pruning. For long time series, consider using e.cp3o_delta.

The returned value is a list with the following components.

`number` |
The estimated number of change points. |

`estimates` |
The location of the change points estimated by the procedure. |

`gofM` |
A vector of goodness of fit values for differing number of change points. The first entry corresponds to when there is only a single change point, the second for when there are two, and so on. |

`cpLoc` |
The list of locations of change points estimated by the procedure for different numbers of change points up to K. |

`time` |
The total amount to time take to estimate the change point locations. |
