owsa_det: One-way sensitivity analysis (OWSA)

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

One-way sensitivity analysis (OWSA)

Description

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

Usage

owsa_det(parms, ranges, nsamps = 100, params_basecase, FUN, outcome,
  strategies = NULL, ...)

Arguments

parms	Vector with strings with the name of the parameters of interest
ranges	A named list of the form c("parm" = 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, owsa_opt_strat and owsa_tornado from dampack

Details

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