Calculate Expected Value of Sample Information (EVSI)
Description
Calculate Expected Value of Sample Information (EVSI)
Usage
calc_evsi(
psa,
wtp,
params = NULL,
outcome = c("nhb", "nmb"),
k = -1,
n = 100,
n0 = 10,
n_by_param = FALSE,
pop = 1,
progress = TRUE
)
Arguments
psa |
object of class psa, produced by |
wtp |
willingness-to-pay threshold |
params |
A vector of parameter names to be analyzed in terms of EVPPI. |
outcome |
either net monetary benefit ( |
k |
basis dimension, if |
n |
additional sample size |
n0 |
initial sample size |
n_by_param |
if |
pop |
scalar that corresponds to the total population |
progress |
|
Value
A list containing 1) a data.frame with WTP thresholds, new prospective sample sizes
(if n_by_param == FALSE
), and corresponding EVSIs
for the selected parameters and 2) a list of metamodels used to estimate EVSI for each
strategy at each willingness to pay threshold.
