OneSampleNormal1 {BayesDIP} | R Documentation |
One sample Normal model with one-parameter unknown, given variance
Description
For a given planned sample size, the efficacy and futility boundaries, return the power, the type I error, the expected sample size and its standard deviation, the probability of reaching the efficacy and futility boundaries.
Usage
OneSampleNormal1(
prior,
N = 100,
mu0,
mu1,
var,
d = 0,
ps = 0.95,
pf = 0.05,
alternative = c("less", "greater"),
seed = 202209,
sim = 5000
)
Arguments
prior |
A list of length 2 containing the distributional information of the prior. The first element is a number specifying the type of prior. Options are
The second elements of the list is the parameter n0. |
N |
The planned sample size. |
mu0 |
The null mean value, which could be taken as the standard or current mean. |
mu1 |
The mean value of the new treatment. |
var |
The variance |
d |
The target improvement (minimal clinically meaningful difference). |
ps |
The efficacy boundary (upper boundary). |
pf |
The futility boundary (lower boundary). |
alternative |
less (lower values imply greater efficacy) or greater (larger values imply greater efficacy). |
seed |
The seed for simulations. |
sim |
The number of simulations. |
Value
A list of the arguments with method and computed elements.
