enf: expected number of failure in SMART

In wangjunyao0121/RASMART: Response Adaptive Sequencial Multiple Assignments Randomized Trial

Description

expected number of failure in SMART

Usage

enf(
  Q,
  pi1 = c(0.4, 0.35, 0.25),
  pi2 = c(0.35, 0.32, 0.36, 0.56, 0.37, 0.4),
  P = c(1/3, 1/3, 1/3),
  n = 365
)

Arguments

Q	a vector of (Q12, Q21, Q31) for second stage randomization probability in SMART
pi1	the respond rate of treatment 1, 2, 3 in stage I in SMART
pi2	the respond rate for patients who do not respond to a treatment in stage I, but respond to another treatment in stage II
P	Randomization probability in stage I
n	Sample size in SMART

Examples

Q = c(0.5, 0.5, 0.5)
pi1 = c(0.4, 0.35, 0.25)
pi2 = c(0.35, 0.32, 0.36, 0.56, 0.37, 0.4)
P = c(1/3, 1/3, 1/3)
n = 365
