cbfs_red: Generate an artificial event with red noise

In TED: Turbulence Time Series Event Detection and Classification

Description

This function generates a box, cliff-ramp, ramp-cliff or a sine function with red noise (AR(1)) as the background noise. Length of the generated event is 128.

Usage

cbfs_red(type = c("box", "rc", "cr", "sine"), A = 10, s = 1,
  coeff = 0.5)

Arguments

type	type of the event to be generated. There are four options: “box', “rc',“cr',“sine' representing a box, cliff-ramp, ramp-cliff or a sine function.
A	amplitude of the event; default is 10.
s	standard deviation of the AR(1) model innovations. Default is 1.
coeff	coefficient of the AR(1) process, which is used to control the level of red noise. Default is 0.5.

Value

an artificial event with red noise.

Examples

# generate a box function with red noise
set.seed(123)
x = cbfs_red(type = 'box', coeff=0.5, s=1, A=10)
# plot it
plot(x,type='l',xlab='t',ylab='x')
