%description
Chaos theory has been hailed as a revolution of thoughts and attracting
ever increasing attention of many scientists from diverse disciplines.
Chaotic systems are nonlinear deterministic dynamic systems which can
behave like an erratic and apparently random motion. A relevant field
inside chaos theory and nonlinear time series analysis is the detection of
a chaotic behaviour from empirical time series data. One of the main
features of chaos is the well known initial value sensitivity property.
Methods and techniques related to test the hypothesis of chaos try to
quantify the initial value sensitive property estimating the Lyapunov
exponents. The DChaos package provides different useful tools and
efficient algorithms which test robustly the hypothesis of chaos based on
the Lyapunov exponent in order to know if the data generating process
behind time series behave chaotically or not.
