randomization schedule for a study with three arms (a new drug treatment, an active control treatment, and a placebo group). Suppose the sample size in the study is 360. We can write a program to generate the randomization schedule. In practice, block randomization is usually used in this type of study.

Las Vegas algorithms are another class of method which rely on randomization to compute their results. However, in contrast to Las Vegas algorithms, which always produce the exact or correct solution, the accuracy of Monte Carlo methods can only be analyzed from a statistical viewpoint.

Randomization • Allows for some imbalance (like the +1 -1 in AVL trees) • Expected behavior (over the random choices) remains the same as with perfect skip lists. • Idea: Each node is promoted to the next higher level with probability 1/2-Expect 1/2 the nodes at level 1-Expect 1/4 the nodes at level 2• Therefore, expect # of nodes at each level is the same as

Randomization Procedure • Each replicate is randomized separately. • Each treatment has the same probability of being assigned to a given experimental unit within a replicate. • Each treatment must appear at least once per replicate. Example Given four fertilizer rates applied to ‘Amidon’ wheat and three replicates of each treatment.
