optim.samplesize: Calculates the optimal sample size for the future trial.

In annaheath/EVSI: EVSI: Calculating the Expected Value of Sample Information

Calculates the optimal sample size for the future trial.

Description

Calculates the optimal sample size for the future trial.

Usage

optim.samplesize(evsi, setup, pp, Pop, Time, wtp = NULL, Dis = 0.035)

Arguments

evsi	An evsi object that calculates the evsi by sample size
setup	The setup costs of the trial can be given as a vector to represent uncertainty in the costs
pp	The per person cost of the trial, can be given as a vector to represent uncertainty in these costs.
Pop	The incidence population level
Time	The time horizon.
wtp	The willingness-to-pay value
Dis	The Discount rate (default at 0.035)

Value

SS.max The optimal sample size.

ENBS The Expected Net Benefit of Sampling at the optimal sample size

SS.I The interval for which the ENBS is within 5

ENBS.I The ENBS values which correspond to 5 used for plotting purposes.
