example.database3 {TSdist} | R Documentation |
Example synthetic database with series belonging to different classes.
Description
Example synthetic database with ARMA series belonging to 5 different classes.
Usage
data(example.database3);
Format
example.database3
a list conformed of the following two elements:
data The 50 time series are stored in a numeric matrix, row-wise.
classes A numerical vector of length 50 that takes values in {1,2,3,4,5}. Each element in the vector represents the class of one of the series.
Details
example.database3
is a database conformed of 50 series of length 100 obtained from 5 different classes. Each class is obtained from a different initializations of an
ARMA(3,2) process of coefficients AR=(1,-0.24,0.1) and MA=(1,1.2).
Random noise is added to all the series by sampling values from a N(0,1.7)
distribution. R is obtained from the following formula:
Finally, all the series in the database are shifted sh
positions to the right or left, sh
being a random integer value extracted from {-15,...,15}
in each case.
Examples
data(example.database3);
## The "data" element of the list contains the time series, set in a row-wise format.
plot(example.database3$data)[1,]
## The "classes" element in example.database3 contains the classes of the series:
example.database3$classes
