%description
Intervention analysis is used to investigate structural changes in data
resulting from external events. Traditional time series intervention
models, viz. Autoregressive Integrated Moving Average model with
exogeneous variables (ARIMA-X) and Artificial Neural Networks with
exogeneous variables (ANN-X), rely on linear intervention functions such
as step or ramp functions, or their combinations. In this package, the
Gompertz, Logistic, Monomolecular, Richard and Hoerl function have been
used as non-linear intervention function. The equation of the above models
are represented as: Gompertz: A * exp(-B * exp(-k * t)); Logistic: K / (1
+ ((K - N0) / N0) * exp(-r * t)); Monomolecular: A * exp(-k * t); Richard:
A + (K - A) / (1 + exp(-B * (C - t)))^(1/beta) and Hoerl:
a*(b^t)*(t^c).This package introduced algorithm for time series
intervention analysis employing ARIMA and ANN models with a non-linear
intervention function. This package has been developed using algorithm of
Yeasin et al. <doi:10.1016/j.hazadv.2023.100325> and Paul and Yeasin
<doi:10.1371/journal.pone.0272999>.
