validate_model: Validate model inputs before running

In WARDEN: Workflows for Health Technology Assessments in R using Discrete EveNts

Validate model inputs before running

Description

Performs static checks on the model inputs without running the simulation. Catches common configuration errors early.

Usage

validate_model(
  arm_list = c("int", "noint"),
  init_event_list = NULL,
  evt_react_list = NULL,
  util_ongoing_list = NULL,
  util_instant_list = NULL,
  util_cycle_list = NULL,
  cost_ongoing_list = NULL,
  cost_instant_list = NULL,
  cost_cycle_list = NULL,
  other_ongoing_list = NULL,
  other_instant_list = NULL,
  npats = 500,
  n_sim = 1,
  psa_bool = NULL,
  seed = NULL
)

Arguments

arm_list	Character vector of intervention names.
init_event_list	List of initial events and event times (output of add_tte()).
evt_react_list	List of event reactions (output of add_reactevt()).
util_ongoing_list	Character vector of ongoing QALY variable names.
util_instant_list	Character vector of instant QALY variable names.
util_cycle_list	Character vector of cycle QALY variable names.
cost_ongoing_list	Character vector of ongoing cost variable names.
cost_instant_list	Character vector of instant cost variable names.
cost_cycle_list	Character vector of cycle cost variable names.
other_ongoing_list	Character vector of other ongoing variable names.
other_instant_list	Character vector of other instant variable names.
npats	Integer. Number of patients per simulation.
n_sim	Integer. Number of simulations.
psa_bool	Logical. Whether PSA mode is intended.
seed	Numeric. Random seed.

Value

Invisibly TRUE if all checks pass. Prints a summary of checks.
