| Two key elements in any experimental design are randomization and replication. |
| We extend the methodology of single block randomization to allocate to multiple blocks conditioning on previous allocations. |
| As the titles suggest, the two workshops focus on approximation algorithms and randomization. |
| All eligible patients were assigned to each group by simple randomization with rigorous allocation concealment. |
| Although lack of generalizability is often cited as the major shortcoming of randomization tests, other limitations have also been discussed. |
| Before randomization, patients were stratified according to tumor resection status. |
