This is a high-level function that calculates global complexity measures directly from a given time series or ordinal pattern distribution.

1 | ```
global_complexity(x = NA, opd = NA, ndemb)
``` |

`x` |
(OPTIONAL) If opd is not specified, a time series vector x must be specified |

`opd` |
A numeric vector that details an ordinal pattern distribution in a user-specified permutation coding scheme. |

`ndemb` |
(OPTIONAL) If x is given, the embedding dimension (ndemb) is required. |

This function calculates the following global measures of complexity and information:

Permutation Entropy (PE, cf. Bandt and Pompe, 2002)

Permutation Statistical complexity (MPR complexity, cf. Martin, Plastino and Rosso, 2006)

Number of "forbiden patterns" (cf. Amigo 2010)

A named vector containing the three global complexity measures.
