twsa_det: Two-way sensitivity analysis (TWSA)

In DARTH-git/darthpack: The Decision Analysis in R for Technologies in Health (DARTH) coding framework

Two-way sensitivity analysis (TWSA)

Description

This function runs a deterministic two-way sensitivity analysis (TWSA) on a given function that produces outcomes.

Usage

twsa_det(parm1, parm2, ranges, nsamps = 40, params_basecase, FUN,
  outcome, strategies = NULL, ...)

Arguments

parm1	String with the name of the first parameter of interest
parm2	String with the name of the second parameter of interest
ranges	A named list of the form list("parm1" = c(0, 1), ...) that gives the ranges for the parameters of interest. The number of samples from this range is determined by nsamp
nsamps	number of parameter values. If NULL, 100 parameter values are used
params_basecase	List with parameters for the base case
FUN	Function that takes params_basecase and ... and produces outcome of interest
outcome	String with the outcome of interest produced by nsamp
strategies	vector of strategy names. The default (NULL) will use strategy names in FUN
...	Further arguments to FUN (not used)

Value

A dataframe with the results of the sensitivity analysis. Can be visualized with plot.owsa, and owsa_tornado

Details

FUN must return a dataframe where the first column are the strategy names and the rest of the columns must be outcomes.
