Description Usage Arguments Details Value Author(s) References See Also Examples

A codebook contains the permutation distribution of a time series.

1	codebook(x, m = 3, t = 1, use.fast=T, normalized = T)

`x`	a vector ot a time series
`m`	The embedding dimension.
`t`	Time-delay of the embedding.
`use.fast`	Use a fast C-implementation if possible.
`normalized`	Normalize codebook such that it is a probability distribution.

The length of a codebook is the factorial of the embedding dimension. The elements of the codebook represent relative frequencies of codewords of size m.

Returns a vector of relative frequencies.
