odeBruitMult2: For the numerical integration of ordinary differential...

In GPoM: Generalized Polynomial Modelling

For the numerical integration of ordinary differential equations with dynamical noise.

Description

A subfunction for the numerical integration of Ordinary Differential Equations provided in a generic polynomial form. Model formulation follows the convention defined by function poLabs.

Usage

odeBruitMult2(
  x0,
  t,
  K,
  varData = NULL,
  txVarBruitM = NULL,
  varBruitM = NULL,
  method = NULL
)

Arguments

x0	Initial conditions
t	All the dates for which the result of the numerical integration of the model must be provided
K	A matrix providing the model description: each column corresponds to one equation which polynomial organisation is following the convention defined by function poLabs.
varData	A vector of size nVar providing the caracteristic variances of each variable of the dynamical systems in ODE defined by matrix K. If not provided, this variance is automatically estimated.
txVarBruitM	A vector defining the ratio of DYNAMICAL noise for each variable of the dynamical system in ODE. This noise is a perturbation added at each numerical integration step. The ratio is defined relatively to the signal variance of each variable.
varBruitM	A vector defining the variance of DYNAMICAL noise for each variable of the dynamical system in ODE. This noise is a perturbation added at each numerical integration step.
method	Numerical method used in the integration process. (see ode function in deSolve package for details).
