Constructor method of "odemodel" class

Description

Constructor method of "odemodel" class

Usage

## S4 method for signature 'odemodel'
initialize(
  .Object,
  name,
  model,
  observation,
  initial,
  par,
  link,
  diffnames,
  keep_sensitivity = TRUE,
  call
)

Arguments

.Object	object
name	name of the model
model	ode model
observation	observation model
initial	initial values
par	model parameters
link	link functions for parameters (log links are used as default)
diffnames	optional character vector specifying the names of a variable for which the consecutive difference needs to be calculated
keep_sensitivity	(logical) maintain the Jacobian as a part of the model object?
call	original function call

Value

An object of class “odemodel” as described in odemodel-class.

Examples

SI_model <- odemodel(
    name = "SI",
    model = list(
        S ~ - beta*S*I/N,
        I ~ beta*S*I/N - gamma*I
    ),
    observation = list(
        susceptible ~ dnorm(mean=S, sd=sigma1),
        infected ~ dnorm(mean=I, sd=sigma2)
    ),
    initial = list(
        S ~ N * (1 - i0),
        I ~ N * i0
    ),
    par = c("beta", "gamma", "N", "i0", "sigma1", "sigma2"),
    link = c(i0="logit")
)
