h_model_dual_endpoint_beta: Update certain components of 'DualEndpoint' model with regard...

In Roche/crmPack: Object-Oriented Implementation of CRM Designs

Update certain components of DualEndpoint model with regard to parameters of the function that models dose-biomarker relationship defined in the DualEndpointBeta class.

Description

A simple helper function that takes DualEndpoint object and updates use_fixed, priormodel, modelspecs, init, sample slots with regard to a given parameter of the dose-biomarker relationship f(x) defined in the DualEndpointBeta class. This update solely depends on whether a given parameter's value param is a fixed-valued scalar or two-elements numeric vector. In the later case, it is assumed that param represents two parameters of a probability distribution that will be used in priormodel function to generate values for the param_name parameter of f(x). See the help page for DualEndpointBeta class for more details.

Usage

h_model_dual_endpoint_beta(
  param,
  param_name,
  param_suffix = c("_low", "_high"),
  priormodel = NULL,
  de
)

Arguments

param	(numeric) the value of a given param_name parameter of the dose-biomarker relationship function f(x). Either a fixed-valued scalar or vector with two elements that are the parameters of a probability distribution that will be used in priormodel function to generate values for the param_name parameter of f(x).
param_name	(string) the name of the parameter of f(x), whose value depends on param.
param_suffix	(character) the two suffixes to be appended to the elements of param_name and then used when updating modelspecs. The value of this argument is ignored when param is a scalar.
priormodel	(function or NULL) a function representing the JAGS prior specification that will be appended to existing de@priormodel specification if param is not a scalar. Otherwise, de@priormodel remains unchanged.
de	(DualEnpoint) dual endpoint model whose slots will be updated.

Value

A DualEndpoint model with updated use_fixed, priormodel, modelspecs, init, sample slots.
