CovAdptRnd: Generate treatment assignment under various CARs

In drcarlate: Improving Estimation Efficiency in CAR with Imperfect Compliance

Generate treatment assignment under various CARs

Description

Generate treatment assignment under various CARs.

Usage

CovAdptRnd(rndflag, S, pi)

Arguments

rndflag	Index of the assignment rule. 1 for SRS; 2 for WEI; 3 for BCD; 4 for SBR
S	A nx1 vector.
pi	Targeted assignment probability across strata. It should be a vector with the length of max(S), It should be noted that the treatment assignment process is independent of pi when rndflag == 2 or 3.

Value

A nx1 treatment assignment vector generated according to the specified method.

Examples

CovAdptRnd(rndflag = 1, S = matrix(sample(1:4,100,TRUE)), pi = c(0.5, 0.5, 0.5, 0.5))
CovAdptRnd(rndflag = 2, S = matrix(sample(1:4,100,TRUE)), pi = c(0.5, 0.5, 0.5, 0.5))
CovAdptRnd(rndflag = 3, S = matrix(sample(1:4,100,TRUE)), pi = c(0.5, 0.5, 0.5, 0.5))
CovAdptRnd(rndflag = 4, S = matrix(sample(1:4,100,TRUE)), pi = c(0.5, 0.5, 0.5, 0.5))
