Description

Generate permuted block treatment assignments

Usage

Value

A vector of treatment assignments with labels from the `trt_label` argument, based on stratified permuted block randomization.

Arguments

z

The car_strata design matrix, as a data frame with factor variables

trt_label

Treatment label

trt_alc

Treatment allocation vector

blocksize

Permuted block blocksize

Examples

# Create car_strata variables
library(fastDummies)
library(dplyr)

x <- runif(100)
z <- cut(x, breaks=c(0, 0.25, 0.5, 0.75, 1.0))
z <- dummy_cols(z) %>%
     mutate(across(where(is.numeric), as.factor))

car_pb(z[, 2:5], c(0, 1, 2), trt_alc=c(1/4, 1/2, 1/4), blocksize=4L)
