DualSimulations-class: 'DualSimulations'

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

DualSimulations

Description

This class captures the trial simulations from dual-endpoint model based designs. In comparison to the parent class Simulations, it contains additional slots to capture the dose-biomarker fits, and the sigma2W and rho estimates.

Usage

DualSimulations(rho_est, sigma2w_est, fit_biomarker, ...)

.DefaultDualSimulations()

Arguments

rho_est	(numeric) see DualSimulations
sigma2w_est	(numeric) DualSimulations
fit_biomarker	(list) see DualSimulations
...	additional parameters from Simulations

Slots

rho_est

(numeric)
vector of final posterior median rho estimates

sigma2w_est

(numeric)
vector of final posterior median sigma2W estimates

fit_biomarker

(list)
with the final dose-biomarker curve fits

Note

Typically, end users will not use the .DefaultDualSimulations() function.
