codebook {pdc}

Codebook

Description

A codebook contains the permutation distribution of a time series.

Usage

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

Arguments

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.

Details

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.

Value

Returns a vector of relative frequencies.
