Expected sample size for phase III for time-to-event outcomes
Ed3_tte(HRgo, d2, alpha, beta, w, hr1, hr2, id1, id2, fixed)
HRgo |
threshold value for the go/no-go decision rule |
d2 |
total events for phase II; must be even number |
alpha |
significance level |
beta |
|
w |
weight for mixture prior distribution |
hr1 |
first assumed true treatment effect on HR scale for prior distribution |
hr2 |
second assumed true treatment effect on HR scale for prior distribution |
id1 |
amount of information for |
id2 |
amount of information for |
fixed |
choose if true treatment effects are fixed or random, if TRUE |
The output of the the functions Ed3_tte
is the expected number of events in phase III.
