## Dataset amorese.data.txt

### Description

This data set is a small simulated time series to test the `ACA`

package.

### Format

This data set contains 2 columns. The first column is an index,
from 1 to 410. The second column are the values of a synthetic
combination of normal distributions. This is a modified version of the
data example from James & Mattesons (2014) study: a sequence of 100
independent samples from normal distributions (N(0, 1), N(0, 3), N(2, 1)
and N(2, 4)). The notation N(??, ??) means normally distributed
with mean ?? and standard deviation ??. This synthetic data set is
slighty upgraded by adding an extra N(0, 3) very short (10 samples)
segment at the end of the initial sequence. This extra tip is added in
order to assess the detection capability for a breakpoint close to
series??? end, where an edge effect may be significant. Moreover, a 5 per
cent slope is added to this synthetic series to simulate a series with
upward trend. This synthetic series is plotted in Figures 2b and 2d in
Amorese & al. (2018).
