Forcing with Trivial Modules

Source: R/trivial.R
xds_info_trivial_forcing.Rd

Trivial modules were developed for each one of the three dynamical components, making it possible to develop studies of some focal process with known inputs: a trace function approach.

The trivial modules and EIR forcing (see xds_setup_eir) construct trace functions as composed time series functions. The value of a forced variable \(x(t)\) is computed as a product of four configurable elements:

  • \(\bar x\): a mean value

  • \(F_S(t, V)\): a seasonal pattern

  • \(F_T(t, V)\): a trend

  • \(F_K(t, V)\): a shock

$$x(t) = \bar x \times F_S(t, V) \times F_T(t,V) \times F_K(t, V)$$

  • A trace function library for RAMP is in ramp.func

  • Functions that integrate ramp.func and ramp.xds are found in ramp.forcing

For a discussion of mechanistic approaches to forcing, see SimBA: Trace Functions
