Computation of weighted ordinal patterns of a time series. Weights can be generated by a user-specified function (e.g. variance-weighted, see Fadlallah et al 2013).

1 | ```
weighted_ordinal_pattern_distribution(x, ndemb)
``` |

`x` |
A numeric vector (e.g. a time series), from which the weighted ordinal pattern distribution is to be calculated |

`ndemb` |
Embedding dimension of the ordinal patterns (i.e. sliding window size). Should be chosen such as length(x) >> ndemb |

This function returns the distribution of weighted ordinal patterns using the Keller coding scheme, detailed in Physica A 356 (2005) 114-120. NA values are allowed. The function uses old and slow R routines and is only maintained for comparability. For faster routines, see weighted_ordinal_pattern_distribution.

A character vector of length factorial(ndemb) is returned.
