ocs_exp_covar {BPrinStratTTE}

Determine operating characteristics of fits from two-arm trials with an exponentially distributed time-to-event endpoint and one predictor of the intercurrent event

Description

Determine operating characteristics of fits from two-arm trials with an exponentially distributed time-to-event endpoint and one predictor of the intercurrent event

Usage

ocs_exp_covar(multiple_fits, d_params, m_params)

Arguments

multiple_fits

List of model fits from fit_mult_exp_covar.

d_params

List of data parameters as used in sim_dat_one_trial_exp_covar.

m_params

List of model parameters as used in fit_single_exp_covar.

Details

This function is used in run_sim_exp_covar(), the output of the two functions is the same.

Value

A list of length 3, containing objects call ocs, d_params, m_params, where ocs is a tibble containing averaged parameter estimates and operating characteristics, and d_params and m_params are the objects supplied to the function.
