model: model object constructor.

In BaM-tools/RBaM: Bayesian Modeling: Estimate a Computer Model and Make Uncertain Predictions

model object constructor.

Description

Creates a new instance of a 'model' object

Usage

model(
  fname = "Config_Model.txt",
  ID = "Linear",
  nX = 1,
  nY = 1,
  par = list(parameter("Xeffect", 1, prior.dist = "FlatPrior")),
  xtra = xtraModelInfo()
)

Arguments

fname	Character, configuration file name.
ID	Character, model ID. Type 'getCatalogue()' for available models.
nX	Integer, number of input variables.
nY	Integer, number of output variables.
par	list of parameter objects, parameters of the model.
xtra	xtraModelInfo object.

Value

An object of class 'model'.

Examples

# defaut linear regression model Y=aX+b
mod <- model()
# BaRatin model for a single-control rating curve Y=a(X-b)^c
mod <- model(ID='BaRatin',nX=1,nY=1,
             par=list(parameter('a',10,prior.dist='LogNormal',prior.par=c(log(10),0.1)),
                      parameter('b',-1,prior.dist='Gaussian',prior.par=c(-1,1)),
                      parameter('c',5/3,prior.dist='Gaussian',prior.par=c(5/3,0.05))),
             xtra=xtraModelInfo(object=matrix(1,nrow=1,ncol=1)))
