The spоnsоr wоuld like to hаve а bаlance of smoker/non-smoker within each center. I am considering two proposals: 1. Use minimization to balance on two covariates: center and smoking status. 2. Randomize within each center, preparing two separate randomization sequences—one for smokers and one for non-smokers. Each sequence would use permuted blocks with a size of 4. Which proposal would be better? Please briefly explain your reasoning.
