markov_ce_pipeline: Markov Sampling, Simulation, and Cost Effectiveness Analysis...

In seabbs/SpeedyMarkov: Speed up Discrete Markov Model Cost Effectiveness Simulations

Description

This functions wraps multiple modular functions and allows an end-to-end cost effectiveness to be run, including final analysis of the findings.

Usage

markov_ce_pipeline(
  markov_model = NULL,
  duration = NULL,
  discount = 1.035,
  samples = 1,
  baseline = 1,
  willingness_to_pay_threshold = 20000,
  sample_type = "rcpp",
  sim_type = "armadillo_all",
  debug = FALSE,
  batches = 1,
  batch_fn = NULL,
  ...
)

Arguments

markov_model	A list of functions that define a markov model across multiple interventions. See example_two_state_markov for the correct format.
duration	Numeric, how many long to run the model for.
discount	Numeric, the discount that should be applied to the costs and QALYs. Defaults to 1.035.
samples	Numeric, defaults to 1. The number of markov model samples to use.
baseline	Numeric, the intervention to consider as the baseline for pairwise comparisons.
willingness_to_pay_threshold	Numeric, defaulting to 20,000. This is the threshold at which an intervention may be considered cost effective in the UK.
sample_type	A character string specifying the approach to use to sample the model. Options and defaults inherited from sample_markov.
sim_type	A character string specifying the approach to use to simulate the model. Options and defaults inherited from simulate_markov.
debug	Logical, defaults to FALSE. Turns on all debug checks - this may impact runtimes.
batches	Numeric, defaults to 1. The number of batches to run simulation/sampling in. When set to values greater than 1 a batch_fn must also be supplied. It is likely that the most efficient option will be to use a batch number that corresponds to the number of cores being utilised.
batch_fn	Function, defaults to NULL. This is the function to be used to parallise across batches. Potential options include parallel::mclapply (not Windows) or furrr::future_map (requires the use of future::plan outside the function). When not given the function will default to using no batching.
...	Additional options to pass to batch_fn. For example this may be the mc.cores argument of parallel::mclapply.

Value

A list containing the model samples and simulations and cost effectiveness summary measures.
