A concept of model-robustness is defined in terms of the performance of the design in the presence of model violations. The robustness problem is discussed for several randomization procedures ...

You can use the PLAN procedure to design a completely randomized design. Suppose you have 12 experimental units, and want to assign one of two treatments to each unit. Use a DATA step to store the ...

References on sample size calculations for randomized studies with a continuous response are abundant. The sample size is usually calculated from a simple two-sample ...
