ProteinSequences

Description

Categorical time series (CTS) of protein sequences from different species

Usage

data(ProteinSequences)

Format

A tsibble with four columns, which are:

Value

The categorical values of the time series in the dataset.

Series

Integer values indicating the considered time series (there are 40 time series in the dataset).

Time

Integer values indicating the temporal indexes of the observations.

Class

Integer values indicating the class of each time series.

Details

The column Value is the concatenation of 40 time series taking four categorical values (amino-acids). The column Class is formed by integers from 1 to 4, indicating that there are 4 different classes in the database. Each class is associated with a different family of viruses. For more information, see López-Oriona et al. (2023).
