is.model {LaplacesDemon}

Logical Check of a Model

Description

This function provides a logical test of whether or not a Model specification function meets mininum requirements to be considered as such.

Usage

is.model(Model, Initial.Values, Data)

Arguments

Model

This is a model specification function. For more information, see the LaplacesDemon function.

Initial.Values

This is a vector of initial values, or current parameter values. For more information, see the LaplacesDemon function.

Data

This is a list of data. For more information, see the LaplacesDemon function.

Details

This function tests for minimum criteria for Model to be considered a model specification function. Specifically, it tests:

• Model must be a function

• Model must execute without errors

• Model must return a list

• Model must have five components in the list

• The first component must be named LP and have length 1

• The second component must be named Dev and have length 1

• The third component must be named Monitor

• The lengths of Monitor and mon.names must be equal

• The fourth component must be named yhat

• The fifth component must be named parm

• The lengths of parm and parm.names must be equal

This function is not extensive, and checks only for these minimum criteria. Additional checks are conducted in IterativeQuadrature, LaplaceApproximation, LaplacesDemon, PMC, and VariationalBayes.

Value

The is.model function returns a logical value of TRUE when Model meets minimum criteria of a model specification function, and FALSE otherwise.
